Words, words, words. How many times a start-up pledges something (like, being there to actually solve a problem for users) only to get to "an exit" and disappear, selling on shutting down the product? Even if they really believe what they say (for which their cliché-laden copy is a negative evidence in my book), investors will want their returns. I don't think they're gonna pull this off with micropayments.

I need more than a pledge to start believing in a VC-backed startup.
