I'm not sure if it's intentional or not but people's signatures are showing without separators and in the same font as the main post text which makes them really hard to tell apart.
Seen this at least on the most recent Chrome and Firefox on OS X and I pretty sure I've seen it on Windows 7 as well.
That's something that is more complicated than it seems, but we are indeed working on it.
Also, I'd like to have the type display just a tick or two larger. At least that can be affected with keyboard shortcuts- command and + or - on a Mac, control and + or - in Windows.
I assumed it wasn't going to be easy but I also wasn't convinced that it wasn't a problem at my end...
And while I'm nitpicking 
, the canoe comment in this post doesn't seem to collapse either, although its title says it does:

It collapses for other users; if you were to log out and then back in it should appear collapsed. (Or on your next visit)
In the best case scenario, it will be gone before you get back. 
Hopefully I'm not just repeating what someone else has observed in another thread, but...
I tried to watch/follow/subscribe to a post I just made to catch the answers,and I got the "404 Explodey" page.
(Er, I mean to say I got the "get out the map" page, just because it's lousy form not to be specific when reporting an error, no matter how badly you want to attempt humor...)
There are a few thread tools that have gone on the blink after the redesign; we're working through them. Very shortly, the signatures should be visibly different from the body of these posts, then there are a few other user profile issues to work out, and then the thread subscription issue is on deck.
