Well, I guess you can't improve if you never get feedback, so I'll do my part!
I've been on this site since it was Yiffstar, as I'm sure many others have, and out of the different versions of the site, I like regular SoFurry the best. It's only because the watchlist and featured were cleaner. When I go to my watchlist here it's a cluster of journals, stories, art, music, all that jazz. It's easy to fix though by simply clicking on the 'artwork' or 'stories' tab to organize it all, so it's just an extra step for cleanliness.
However, 2.0 is really nice to look at, and it's faster, and I just generally like how it's set up!
(If I've been unclear, lemme know, I'm not good with explaining stuff online >_> )
Keep it up SoFurry team!
