@Hoople, Now that it has been close to a year and I've:
1. Deindexed many pages
2. Improved user metrics
3. Improved content
4. Added new great content
I'm thinking more and more about the link theory... aside from some small changes left to do... links is the only real frontier I haven't worked on for a year...
Anybody else going down the link path for Panda with good results?
