I hear you, and it might be worth noting this analysis is looking for big changes in a positive direction (it's geared toward investors looking for early upside), and Imgur increased downloads by 200% last week. Time will tell where they're headed. They have a huge web presence.

The #1 startup for mobile, in the overall sense, is Rdio. But we're trying to catch stuff in the way up, so we weigh more heavily toward change in momentum. There is probably another good list I can release later this week that has more of the "usual suspects" you'd expect to see.
