Its too early to issue final conclusions about the impact of current algo update over your sites. Please don't give up. The rollout has just started, and as any other previous algo updates, things change during different stages of the rollout. Wish you luck.
Btw.. I understand from one of Matt Cutts tweets today that he would probably be asking for feedback regarding current algo update when more rollout progress. Hopefully people would be able to report collateral damages of the current algo update too.
