I like the site, like the idea, and I'm looking forward to reading more reviews. My only comment is that the "speak" form on the left hand side seems kind of out of place and disconnected from the rest of the site. Took me a while to figure out what it was for. Also - if you insist on keeping it there, some kind of differentiation between search and speak would be nice. At a glance it looks like they're part of the same form.
This comes from a guy with 1920 x 1200 in Firefox, but I tried shrinking the window and felt the same way.
