Back in the early days of instant messaging (IM), users could only IM other users through the same IM platform. If you were using AOL Instant Messaging (AIM) then you could only chat with another AIM member. Thankfully, that's no longer the case. There are a variety of chat clients available that provide multi-client support to enable you and your pals to IM regardless of the IM service that they're using. Why would you want to use IM? For a variety of beneficial reasons. IM allows instant communication between people, which can save time and money. No long distance charges apply and it transmits information quickly to simulate the natural flow of conversation. It can reduce the amount of email sent, conference calls scheduled and IM is capable of holding multiple sessions with many people. IM can also be integrated into your existing website, which makes it a fantastic customer service tool. There are more than 80 chat client applications available and each one has its pros and cons. The list was whittled down based on social media integration, multi-client platform capabilities and number of supported chat networks. Knowing what chat clients are available and what some of their key features are can be helpful in determining what will be the best solution for you. NOTE: Most of these applications have mobile access from your handheld, however, not all mentions were included in this blog post. Here’s an alphabetical roll call that features six of the best:

Adium

Let me start with an apology to my PC peeps. The first chat client on the list is for Mac users only (promise that the remaining reviews will be more embracing of both operating systems). Adium started in September 2001 and has grown rapidly among Mac users in terms of popularity. One of Adium’s more notable features involves contact management. Contacts can be combined, which allows you to merge your contacts so that each one represents a person, not an account. A great way to keep things organized. Customizing Adium is accomplished through a suite of Xtras. Everything from layout and themes to sounds, emoticons and message styles. The sky’s the limit with Adium. One of the main reason for using Adium is that it integrates with Facebook Chat and Twitter. This makes it incredibly convenient to monitor direct messages from Twitter and IMs from Facebook through one central location. The Twitter Currently, Adium is 100% freeware and it supports more than 17 chat networks.

Digsby

By a huge margin, Digsby is one of the most comprehensive multi-client chat clients available. First off, it plays well with Windows, Mac and Linux. Next, its features are so robust that not listing some of the standouts would be a disservice.

• Chat with visitors and friends by placing a widget on your blog, website or social media profile
• Manage your Hotmail, Gmail, Yahoo! Mail, AOL/AIM Mail, IMAP and POP accounts from Digsby
• Manage multiple conversations with tabbed windows
• Use a combined buddy list for all your contacts regardless of chat platform and rename them with an alias to eliminate hard to remember chat handles like ‘pinkbunny25’
• Audio and video chat availability (good-bye Skype)
• Complete customization with Digsby application skins and themes

Pretty amazing considering that Digsby has only been around since January 2008. So what can it do with your social media networks? Quite a bit. Digsby supports Facebook, Twitter, LinkedIn and MySpace. You can receive alerts for new friend requests, messages and event invites, plus get a newsfeed of everyone’s status updates. The bonus of bonuses is that you can update your own status for all four networks with Digsby. A total of seven chat networks are supported including, Windows LIve, AIM, ICQ, MobileMe, XMPP and Yahoo! IM and Facebook Chat.

Meebo

The main difference between Meebo and the other applications reviewed is that Meebo isn’t really a ‘desktop’ chat client. It’s web-based, but can be used through a widget that users can embed in their blogs or websites, as well as the Meebo Bar, which is a gadget that lets users connect to Meebo through the base of a webpage. Meebo’s more of a pseudo-desktop chat client that's housed through your browser. Like the widget, it can be incorporated into the bottom pages of your website. Meebo is IM in a web page. Just go to the Meebo site, login and you’re instantly connected to all of your chat buddies through your Meebo account. The benefit of a web-based client is that you eliminate the hassle of software installation and you always have instant access to IM as long as you can find an internet connection. Meebo offers video and audio chat, as well as file transfer. You could potentially take chatting from something you do with friends to a fresh way to conduct business conference calls and meetings. It’s convenient and flexible.

• Because of Meebo’s online interface, it has an array of fantastic features that can’t be found with other desktop chat clients.
• Mobile access was mentioned earlier, but Meebo is built for iPhone, Android and other web-based handsets.
• Join Meebo rooms to meet and connect with new users, or create a custom Meebo room of your own and feature it on your website or blog. A super way to harness conversations about you and your business in primary place.
• Notifications are sent to an icon in your system tray so you’ll never miss anyone who’s trying to contact you.
• A snappy FireFox extension allows for easy integration of Meebo.
• Have a restricted computer (hardcore firewalls or an IT policing department on steroids)? The Meebo Repeater is a beta version of downloadable software that enables chat when IM access is restricted.
• Excellent analytic tool to monitor and track information about your site.
• Connect your Meebo bar to any social media site and drag headlines and links to share through those sites.

Last but not least, Meebo lets users advertise. You can see one of the ad options in action on the Meebo Bar and click it to see even more. You’ll need to contact Meebo directly to learn more about pricing and program options based on your budget and objectives. Meebo connects you to Facebook and five other chat networks. It would be nice to see Meebo offer additional social media site support, but for now you have access to the biggest of the bunch.

Nimbuzz

With Nimbuzz, users can choose to use it as a desktop chat client for Windows or Mac, a web-based client or mobile client. For users who aren’t looking for all the bells and whistles, or anyone who feels a little intimidated by choices, Nimbuzz is your solution. It’s incredibly lite, maybe too much, like  feather actually, as far as features go. In a nutshell, Nimbuzz supports around 12 chat networks, including Facebook and MySpace (at the time of this writing details on support for Twitter couldn’t be located). Nimbuzz also has a secondary service called NimbuzzOut that works as an internet phone service through their IM application. A better way of explaining this would be to call it Skype with fewer features and branded with a new name. There’s not too much more to share about Nimbuzz, other than it’s a plain and simple multi-client chat product. If you’re new to the world of IM, Nimbuzz could be a good starter application. Once you get situated you may find yourself wanting other features and you can always experiment with a new product as your needs grow.

Trillian Astra

Now it’s my turn to apologize to Mac users - at this time, Trillian Astra is only available for Windows, but a version of Max OS X is in the works. In the meantime, Mac users can still use Trillian and experience it through the web-based version. All is not lost fellow Appleheads. Developed by Cerulean Studios, Trillian Astra a real powerhouse in the desktop chat client realm. The functionality that it delivers makes it a truly outstanding tool and one that you’ll want to have in your social media arsenal. Trillian boasts 450+ features to help organize your online life. Facebook, Twitter and MySpaceIM have been incorporated into Trillian’s social media round-up. An added network that many users see as a ‘deal maker’ is the inclusion of Skype. Through its applications, users can place Skype calls, control group conversations, support multiple identities (nice for personal and business profiles) and work with file transfer protocols. Sweet indeed! Trillian Astra aligns more closely with Digsby. It has many features in common (not all) like support for more than nine chat networks and email capabilities. Customization on the surface is accommodated with plugins, skins and themes and usage management that enables you to optimize performance, have proxy control and hands-on identity and connection management.

VoxOx

VoxOx is one serious hybrid. It’s part Adium, Digsby and Skype all rolled into one interface. You can make phone calls, send IMs and emails, monitor social media, share updates and a whole lot more. A quick summary:

• Social networking
• Text messaging
• Instant messaging
• Voice calling
• File sharing
• Email
• Fax

VoxOx has also kicked it up a notch with their universal translator. Whatever you’re typing can easily be converted into the language of your choice. Check out the VoxOx list to see what countries are supported. Another swanky feature is the VoxOx Personal Assistant (VOPA). She’s the real deal and she also puts celebrity assistants to shame with her admin skills. She can screen your calls, eavesdrop on voicemails to see if you should pick-up or let it roll on through and coordinate fax pick-up. The VOPA also offers a ‘Stalker Feature’ and caller ID spoofing. The Stalker Feature let’s VOPA send out a busy signal, disconnected message or personal greeting recorded for any specific person that you’d like to avoid. Caller ID spoofing let’s you create a customized number that others see when you contact them. You could create something easy to remember or spell out something fun. Endless possibilities. Last, but not least, you can include ringback tones to identify clients, friends or family and set-up on-hold music when calls are in queue. Social media coordination with Facebook, Twitter and MySpace (hey, where’s LinkedIn?) let you share videos, pictures, update your status, chat with friends and reply to Tweets. Now that LinkedIn has opened up its API to developers, VoxOx may integrate this social network in the future.

HONORABLE MENTION

Pidgin is a free downloadable chat client that make is very easy to connect with just about anyone. Pidgin supports 17 different chat networks, however, it’s only available for Mac. It’s been around since 1998 and has more than 3 million users.
