Honestly I haven't thought he would manage to raise this amount.
I just checked at on 8 and it was 43%. After that I didn't look into the count. Now, wow I'm impressed. I think this is the best crowdfunding effort I've ever seen.
I'm not a backer of app.net. But would love to hear about the roadmap and future development. Still twitter, FB is OK for me. I'm waiting for what app.net can offer something I wanted.
BTW I'm not a hater :)
Good Luck! App.net team.
