Also - it appears that a lot of sites that were hit by Google's October adjustment to filters were so-called "white-hat" sites.
I think the problem is that in recent years white hat has come to mean not doing any backlinking at all, and relying purely on maximising on-page factors. And black hat has come to mean focusing purely on backlinks and ignoring the on-page stuff.
The problem is that Google sees on-page SEO as dirtier than off-page SEO (because it's easier to do and therefore easier to overdo).
I think people need to forget about hats, dial back on the on-page stuff, and start doing some mild backlinking. There is absolutely nothing wrong with issuing a bunch of press-releases to various sites and promoting your page.
Not doing so is akin to someone opening a shop and refusing to issue fliers, or tell the local paper where the address of the shop is. That model hasn't worked in a good 500 years and isn't working online either.
Just my two cents.
