I didn't, thanks, it looks pretty similar to what I meant.

I would like it to be "more wiki", coderwall seems more a social profile where you can share small tips, not a wiki where you can write whatever you want.

It's also missing the "git" stuff, which I think could be huge (or maybe it's just silly, but it sounds good in my head).

And I also don't really like the "closeness" of the site. for example I can't even see every tip shared by an user without having an account (it just show the first ones and then a blurry mess, a-la Quora).
