Ask HN: Review my app, ChatThrough.com

Hey HN, My partner and I recently launched http://ChatThrough.com a site for finding and creating random-chat groups.

Can you guys take a look at it and see whether you have any suggestions or advice for us?

I'm not a designer and I had to design the site, so if anyone has any tips for improving the overall design.

Also we're curious as to how we can attract users.

Thankyou for your help! (check out blog.chatthrough.com for further info)
