I think it's great you decided to pursue the idea until fruition regardless of how well things weren't going with your friends and team. It's hard to get anything done when the other teammates don't have the passion or ethic to see it through. Kudos to you to launching it.

As to the person who asked what does this solve? What did Instagram solve? What does Twitter solve or Lolcats or Angry Birds or Reddit? Sometimes providing reprieve from a day or entertainment/inspiration is enough.
