I vote for TweeGo. First of all I don't have the heart to vote my own app DropN900

I actually used TweeGo to monitor the DropBoxApi twitter channel for announcements when I developed my own entry for this competition. Also I went and read the source code a little bit from gitorious and I really like the way you use Qt, seems very professional C++/Qt usage. Easy to read and see whats going on. I especially appreciate the amount of work you have put to the UI code. Very good work.
