120 for me. It incorporates the multiple lines, and conveys a lot of action with those lines just bursting out. Only thing I'd try to do is emphasize the whole line theme throughout your app so the logo makes a bit more sense. But it's definitely the most polished, professional, and exciting one for me.<p>On a side note, it's interesting to see some of the logos so blatantly rip off Plaxo's.
