Here is what I can't figure out. One of my sites got hit on the Jan 29th update then a second one with Panda. The one that got hit by panda went from #3 to somewhere on page 5 for its main key phrase. Now given I did have some thin content which I am deleting as I go.
The ones that are in the top positions now is a tgp and a top 100 site. How in the world are they not thin?
