There is no 'suspected Techcrunch fund'. There's a fund created by the founder of TechCrunch, Michael Arrington, named the CrunchFund. (It's a kind of unfortunate name, since it does tie people's minds to TechCrunch.)
Michael Arrington isn't involved in TechCrunch, nor does he have any editorial oversight over it. I don't believe that Michael and Erick Schonfeld (the new editor) are on great terms.
Its just that when Techcrunch fawns over a todo app, it makes me suspect something is up. I am sure nothing is, and its a great app, but Techcrunch is hard to take seriously.
