One Web Messenger for Yahoo!, Google Talk and MSN
Like Meebo, AirTalkr offers a web based instant messenger that lets you stay connected with your buddies on Google Talk, Yahoo! Messenger, Windows Live and other popular IM services.
But there’re a couple of reasons why you may want to give AirTalkr a shot.

Unlike Meebo which is available only for the browser, you can also install AirTalkr IM on your desktop using Adobe AIR runtime. AirTalkr can run on Windows and Mac.
The other useful feature in AirTalkr is something called AirCards. You can view the latest photos that your buddies have uploaded on Flickr, read their most recent blog entries and Twitter tweets right inside AirTalkr.

Pidgin also offers this service. I think it offers more than what airtalkr can give.
What do you say Amit? Am I right?
Pidgin offers the ability to connect to several more types of accounts, including account types that are more popular in regions of the world other than India and the United States. You might want to check that out. It is also cross-platform, and as such can be used by your readers as they leave the corrupt world of Microsoft…
That plus features in ‘AirTalkr’ make the service interesting/fun for using.
I’ll give it a try.
BTW… congratulations for your video presentation at AdSense blog, Amit.
I read your site for a long time, and it’s one of my favorite online destinations.

Amit, Do you know if this works from behind a proxy? i.e., does it have a provision to specify the proxy name and port?
Amit, I also believe that Pidgin is one of the best truly cross platform IM choices with great addon plugins and needs consideration. Off-the-record messaging, extensive IM support (IRC, Jabber, multiple yahoo/gtalk acs), chat history log across all accounts, char count plugin (useful for Twitter users via IM) and Text replacement plugin. To add to all this pidgin is open source and well supported by the community. There are portable versions as well for USB sticks.
