Sorry, post 3, but actually it IS a bit disappointing ;-) I wasn't so disappointed about the YC rejection because of my shoddy application (sorry for that, YC, btw). But this sf0 thing really seems to implement many of my ideas, especially the community implementing the tasks.
Nevertheless I think it would still be fun to work on something like this, perhaps with a different angle. Or what do you think, should I just admit defeat?
