Twitpic is shutting down
Two lessons:1. Don't base your entire business on another business' product.  Especially one that has had such a hostile relationship with third parties.  When the other business decides to discontinue your access to its service, or otherwise change things, or basically copy what you do under their own brand, you're screwed.2. Don't create a similar name that will give you trouble in trademark disputes. (Seriously?  TwitPic? I work in technology, and even I thought they were owned by Twitter, though admittedly, I don't use Twitter much and don't use TwitPic at all).
