Compared to my competitors, the only thing that could have done me in: tags, too many of them. However, I removed them a day after Panda hit on WebmasterCentral [google.com...] and since then traffic has only gone down. I also 'deleted' (at least with a noindex) about 35% of the existing pages, just in case. Google has cached them at least twice since Panda and now most of my site has a March 18 cache, with index and 2 other sections having a daily freshtag. No luck in SERPS though.
Looks, so far, that Google hasn't run the algo on everything after Panda, I can't point at a site that says "we did this and came back."
For a few minutes last night on AOL search, I think, I saw my site's ranking without any 'filters.' Loved it, but it was short lived :)
