Put me in the "dislike" camp. The previous layout had a clean/modern look and this is a step backwards IMO. Can't tell which threads I've already read and the names of people who started the threads is hardly noticeable.
I joined this site because of the people associated with it and the quality of content they put out, so it's not a big deal to me, but the old version was definitely better.
Only my opinion regarding site changes . . .
