Reading builditwith.me is exasperating, they're almost all outdated ideas with trendy buzzwords. "An alarm clock with gamification!"

And then there are gems like this: "What is "Unified Passport System"? It likes Oauth, but it's more complicated." Yeah, because people were complaining that OAuth was too simple ;)

I guess you may find something worthwhile in there, but it seems to me that you can get a better return of your time by looking at what's already out there and thinking on how to improve it.
