I'd substitute the gradients on your site for solid colors, they're a little too intense. Also the signup password field being in plaintext isn't quite right.
I like what Edit Room tries to do but I think you need to look into finding a UX or UI person that understands web design/development because it is a little too geeky/subtle in implementation for the user that this is targeted for. However, I like how it focuses you in on the content and content-type before you get into designing around it.
Thanks very much! I've been working hard on making the UX better, and will have a nice solid update shortly, that should address your concerns. I'll let HN know as soon as the improvements are ready.
One nice thing that's coming is being able to design for different screen widths with a built-in breakpoint tool that creates media queries for you from your design.
