Are you kidding? g### adores WebmasterWorld. Put up a post, and it will be indexed before the page has time to refresh. That's how I found this place.
Well I found a link to WebmasterWorld on another forum. I would say that I haven't found a single useful piece of SEO information on Google - it's all been gleaned by trial and error, and from reading forums and from following links - from one blog post to another, or a forum link to a blog post which links to another forum or another blog post etc etc.
Think of how we found out about the Google guidelines pdf. And PotPieGirl says [warriorforum.com] that she found the document on the Warrior Forum - someone had uploaded it there a few months ago.
Very old school.
This is one industry that doesn't rely on Google to disseminate information. There's food for thought in that!
