My first thoughts when looking at the site:
- Lots of stuff with small text, hard to read and parse what's going on.
- The Suggested Topics at the bottom of each page is weird and kinda pushy.
After a few minutes though, both of those thoughts went away once my eyes got used to it. I still think the Suggested Topics is weird, but it's easy enough to ignore.
EDIT: Having to hit a button to do any replies is also odd. Granted you also had to click into the reply box which equates to the same thing, but the difference in size will take getting used to. Is there a shortcut for bringing up the reply box? That would be aces.
