Really nice! There are many good suggestions in the comments. I'd actually put out some roadmap to the site, and suggest that it is "beta" and is under development, and maybe create an uservoice page and link that from the roadmap, noting that new ideas are welcome, and can be voted on. People like to feel involved in something they like. If they stayed for this long, they may like this, and you may get a hang of what people are missing from the site. (but don't implement every suggestion, just read them)
