Not sure why you got downvoted, it sounds interesting and potentially very valuable. There are few apps that combine the social/shared experience feature with "goal setting", but I haven't observed them being used extensively (outside Duolingo, but even then I don't have a group of "friends" for whom I get regular updates on how they're meeting their goals and an opportunity to give encouragement) and certainly not for activities like reducing how much you're drinking. If I had the time I'd definitely be keen on contributing.
