I've noticed some strange (for me) results in the serps today and yesterday. I seem to be getting a bit of a sitewide slap. Nothing too major, but lots of my low competition stuff has taken a bit of a hit. These are pages that haven't moved in months (years even), and I don't do too much current work on them either. Most of their links came from SEOlinkvine and MAN as well as bookmarking. Everything that I'm currently working on is moving up - so I'm not too fussed, but maybe those networks have been hit by the Panda.
