Google Panda Update 2.2 has gone live On the 4th week June 2011
As Matt Cutts explained, 2.2 was to mainly improve scraper detection and that these Panda updates are pushed out manually.
Not big changes then , some webmaster reported improvement in their ranking after the re
lease.
Google always try to give searcher the best result and to wipe out bad sites.
So basically as I always say , contents first .
Give your visitors a value for the time they spend in your site and you shouldn't worry about Panda or any upcoming animal.
And as google advise make your contents for visitors not for search engines.
As for my site seems the Panda was happy about it, not sure if that was because of the panda or because of some SEO I did to the site in that week
Final tip: scrapers, watch out the Google Panda
