Yes Google 3.3 Panda Right Now Updated Pervious Days .And Its Very Harm Full Clocking Site .and Again His Focus On Good Quality Content.And Now Focus On Micro Bloging Most Like this.
I think unless you are doing that then each time Google roll something you out you are in danger as that is certainly the direction they are going. It’s made me reevaluate my sites and decide which to keep and develop further and which to sell while they are still making money.
Its a great thing to know that Google cares, this Google 3.3 is good because it will make sites to buckle up so that their sites won't be affected by the update.
The only reference to spelling I can see in the update actually concerns Google being able to pick up on mistakes made by a searcher, so that they can recognize the error and still deliver a good result. Although good spelling and grammar is important for the user experience, I don't see anything in the update that suggests it is has become a ranking issue, but if you have seen something, please quote it.
Microblogging, as in Twitter? I can't see any mention of social media in the update. When I searched the document where Google announced the update (http://insidesearch.blogspot.com/2012/02/search-quality-highlights-40-changes.html) the word "social" doesn't appear once. Please state where you have seen information about this?
I think I must have seen a different update to other people, because I can't see anything that would make me want to re-evaluate, sell or buckle up my sites. Google is typically vague about the detail, and many webmasters are typically reading all kinds of things into not only what has been said but what hasn't been said.
