I can only speak for myself. In the first 6 weeks post-Panda 1 in Feb, we threw everything at it. Immediately removing about 10-15% of content (thin).
@synthese - reports are that this is nowhere near strong enough to break Panda. 10-15% insn't exactly throwing much at the problem. I'm seeing well circulated commentary that ratio's as high as 4 spammy pages to 1 good page could be enough to trigger Panda and getting back is tougher than going under.
Eliminate all spam content and start again. That's why some large sites that depend on aggregated / thin content are in trouble - it takes a radical shift in thinking and resources to sort out. And simply writing unique content alone isn't enough. Don't discount links either, even though Panda is on page - crap links to crap pages is a matching disaster.
Some of those sites in the Alexa list were likely big sites? ( even though i would only use the data at best indicative ) Y/N ?
