The proliferation of digital communication means you have to check 50 spots just to see "who wants to bone?" Consolidate thyself, with Digsby.

Designed by a Brooklynite, Digsby's a free IM-like application that also pulls in your existing email and social networking accounts, thus providing a highly organized means for LOLing your life away. Email-wise, Digsby supports web-based clients (AIM/AOL, MSN/Hotmail, Yahoo, etc), plus any POP or IMAP work account, allowing you to respond right through its interface -- bringing together under one time-saving roof all of your personal/professional profiles, plus the aliases you use to anonymously solicit strangers for sinful fudge recipes. Digsby'll also pipe in MySpace and Facebook events, including friend requests, invites, and status updates on mood, dating, even spirituality ("Bob has removed The Bible from his list of favorite books").

So you won't be overloaded, Digsby lets you filter both the types and sources of alerts you want to receive; unfortunately, there's no content filter, so it's on you to delete IMs/emails/status updates that read "who the hell is this?"
