Screenshot / Code Snippet
Stack Overflow/Stack Exchange sites allow you to view questions and filter tags as you please, but only within one site. Considering there is a lot of overlap in certain audiences for certain sites (SO, Software Engineering, Server Fault, DBA, Gamedev, etc etc etc) it would certainly (hopefully!) be useful to some if they could see multiple sites at once. Much like TweetDeck allows users to see multiple "lanes" of tweets, Stackdeck creates multiple lanes (5 in a row with unlimited vertical scrolling) to read.
Haven't picked a license yet but unless SE wants to buy this from me for a million dollars I don't see why it shouldn't be zlib or something similar.

I hope you find Stackdeck useful. I certainly learned a lot making it, which was my intention.
