The penalty is slowling wearing from my sites. I had to do some hardcore stuff the last 3 weeks, but i'm still hanging by a thread. Google doesn't realize what they've done. Some of the most under optimized sites for my niche are now ranking in the top 3 spots where i used to sit. Just keep building quality content and hope for the best.
What do you mean by "expired" domain?This bugged update shit is still going on. I just noticed an expired domain popup to the #1 spot for a relatively big time term with 30k searches a month. This domain wasn't there back when this update first hit, it just appeared yesterday.
Google officially responds in http://googlewebmastercentral.blogspot.com/2012/04/another-step-to-reward-high-quality.html.
Pardon my ignorance, but this IS a "blackhat SEO" forum, right? You're all shocked at google punishing you when you should be doing things properly in the first place. Come on guys, we don't want to be on the same level as the bloody indians et al flooding on to the internet and web dev. markets devaluing our work.
