the Hive Five, Digsby has taken the world by storm since we first mentioned it in February. Boasting integration with all of your IM networks as well as your email
and social networking (Facebook and
MySpace included), Digsby is converting
new users left and right with their simple
but appealing formula: IM + Email + Social
Networking = Digsby. Currently a Windows only app, Digsby's developers
promise that Mac and Linux versions are
in the oven—and that they're constantly squashing bugs from the still-young
Windows version.

Whatsapp For PC for sure is the best app ever created for instant messaging. There is simply no reason why one won't wanna get it on their phone.
