Re: What (specific) pages of the site are most important to you?
Definately recently added anime, that's one thing I miss from v2, having the little link to it at the side. Browse by tag is another part I tend to use more. As for any other links that would be nice to have, I like the idea of having a link to the current season, but I would probably use a link to current year more, i.e. 2008 anime.
Other than that I can't really think of much else. If I want to see a list of the most recent reviews, I just click on the reviews button at the top.
Edit: Ooo actually one thing that could be interesting, more a request or suggestion really, would be a link to a page showing the latest x number of recs. I know it shows the latest recommendation on the anime page but maybe have a list of say today's recommendations or the last 2 days or whatever.
