Thanks so much for your input! A lot of your ideas are close to either things that are planned for the future or ideas that I have discussed with friends.

Badges, for instance, are something that I'm definitely going to implement. And although I think goal-achievement is important, it appears to me that it shouldn't be the only "metric".

For instance, I thought that it would be nice to let a user's friend verify if the picture posted is really compromising, and if it is, award a badge to the user.

Another feature that is definitely coming and that I think will improve "virality" (and that is also similar to something you mentioned) is the ability to set goals (and "bombs") for your friends. Of course they would depend on the friend's approval, but it would be a way to spread the word.

Oh, and honestly I don't think that failed goals are bad marketing. As I see it (and said earlier), I think that fun is our product, not productivity.
