Aye,
Visitors have dropped significantly, although you'd expect that with a disastrous drop in rankings. Having done a little digging, I see the December Panda update may have had some part to play in this.
That said, I stay well away from low quality, panda-targeted sites - although there have been mutterings that it may have been intentional, to encourage particularly profitable AdWords Accounts to spend more. If you've ever run a legal PPC campaign before, you'll know the CPC in many cases is close to extortion.
