We're about to launch, so just about time to throw off the cloak anyways.
Its a videochat website, which if I described you'd immediately compare to Chatroulette. If we don't achieve critical mass early, everyone will leave.
To a degree it is like Chatroulette, though there are different types of rooms and a security mechanism that actually keeps perverts off (you sign in using FB connect, though we never reveal to anyone who you are. This is just to track you so we can block you permanently if reported. And no, you can't create a new FB account and get back on; you have to have 20+ friends to sign in).
If you show up and noone is on the site, you're going to leave and never come back. Thus, need a critical mass to keep it going.
Based on some calculations I've done, to keep a minimum of 50 people on the site at all times we'll need 15k visitors per day.
There are a few other features that I'd be thrilled to go on and on about, but I hope I answered your question. If you're curious and have more questions, you can find my email address in my profile.
