Thanks for your replys.
to confirm to play it safe we have removed the fboo kand twitter buttons and removed the facebook comment plugin.
we still have the latest blog post widget installed but we will remove and revert the old twitter feed if the ranks dont improve.
This will make it 100% back to how it was before the drop.
my question is will Google re-apply the previous metric assuming that the page layout and code is as before and thus move us back to our old SERPs or dose it kinda put you in a "testing" position to "prove yourself".
my assumption is that Google hasn't given us a penalty per say so all the change in rank is due to our page been re-calcualted with a lower metric and thus dropping us a bit.
