I'm doing a (tangentially related) twist on this sort of thing, so I'll ask you the questions that haunted me for months until I could answer them about my own project:

Who's going to use this?

I mean, what's the intersection of people that are computer-articulate enough to know what to ask for ("convert this file for me"), but don't know how to do it, and/or are willing to spend the extra minute or two to post and manage the "favor"? Especially when "know how to do it" means "google for the free web app that does it"?

And who is going to spend their time doing these favors, with no reward except some ethereal concept of "points" that can only be redeemed for doing the things I can already easily do myself (see above)? Realize that you're competing for attention from facebook/twitter/HN. And MTurk, which actually pays.
