What seems strange to me is that they have paying customers who are saying on the support forum that they are getting zero response to their e-mails to the company. Fine, if you're going to shut it down then shut it down, but I wouldn't walk away from paying customers without saying something.
If buxfer is indeed shutting down without saying something to their users, it warrants a Techcrunch post. I would have wanted TC though to have gotten the side of the founders before publishing the story.
