The world was not ready to understand why Tipjoy was such a great idea. When I wish Tipjoy succeeded, I'm mostly wishing the world were different.

Tipjoy had to be shut down by its financial nature. Other sites can stay up on autopilot for a long time. Anyvite grew after its founders moved on, enough so that they recently came back and gave it more attention. Snipshot is one I think could enjoy a rebirth if they made it work on the iPad.
