I found this site looking for a Goodreads-esque experience for my games, and I think I prefer it more than HowLongToBeat and GG.

I think it'd be neat if, similar to the way Goodreads can share your progress updates for books via social media, Completionator could do it for games.

For example, if I read on Goodreads and at the end of my reading session I say I've made it to page 214 or am 36% of the way through a book, if I've offered permission for the site to access my Twitter, it will post to Twitter how far I am through that book. It'd be neat to do so with Completionator when you post that you played X amount of time, for instance.

+1, I think this would be a pretty cool implementation and really add to more of a social dynamic.
