1. No indexed an inactive forum. Account for 1/4 of sites pages.
2. I had a number of Duplicate titles list in WMT (in the 100s).
3. 1/8 of the site had useless UGC, removed it.
4. Fixed header checks to remove (404-like) content listed in WMT.
I'm still working on improving the quality of the pages. For humans the quality is definitely well above average, but there is room for improvement. But I would say as a robot view of my site, it has improved drastically in the last 2 months.
