At $299 / day you better be doing content / image caching and not just handing out origin urls.
$299/day seems kind of steep. Who is this for?
Exactly what I was wondering. Are you just targeting organizers or major conferences or something?
Even then I can't envision how anyone could justify spending $299/day on something like this that (as far as I know, correct me if I'm wrong) can be reproduced for free using the Instagram/Twitter API...
I think the UI could be better. I could see making some very interesting views with famous and this.
