1. Deindexed many pages
2. Improved user metrics
3. Improved content
4. Added new great content
@Lenny2 - just think of things having an end point of being purely mathematical and relationship driven. Panda quality evaluation has to come back to this and it is generally accepted that pure linking is not part of this update. ( but nontheless plays a vital broader role in overall quality signals ).
And those over optimisation elements - do they really act against "quality". Some do, but I'm just re challenging the questions of your perceived over optimization.
So you've been on this for a year, and are only just getting potential signals of a revival in the next iteration [ another thread ]. But even if you get out, how strong will your quality score be - given that you've waited a year. Whatever you've done it isn't enough, and I'm hoping that you are not removing elements which may be beneficial to you. You really deserve a lot better for your efforts and it's great that a Webmasterworld member has come in to assist you.
Can we dig a bit deeper?
In terms of quantity and ratios, how much and what have you improved your content by? How is the content compelling, compared to before - and how would Google be scoring this "mathematically" ?
Google appears to be looking [ in mathematical terms ] for anything that adds value. And since this is a site wide evaluation, I wouldn't be over focusing on just the home page.
