As it stands, the description is quite vague. It might be better to increase the focus on what you feel is the unique selling point of this community, and de-emphasise the stuff that you can do in lots of other places (e.g. share code).

Also, you have a couple of typos and grammar errors on the front page. This isn't a big deal, but it detracts from the feel of a serious project. I'm at work, but if I find time later I'll send you a pull request with some corrections.
