SEOBook author Aaron Wall, has switched his SEOBook product over to a subscription community. I just had a chance to sign up today (link here.) At $100 a month, its not cheap, but you get access to his training program plus exclusive SEO Forum.

I have been a member of several exclusive, paid forums as well as free private communities. The biggest downside is often a loss of momentum due to members cutting their subscriptions. Given how prolific Aaron Wall is with his blog and promoting I am willing to bet this will be a hit.

Microsoft has submitted a $44.6 billion bid to buy Yahoo.

This is the only scenario I can see as someone becoming a serious threat to Google. Yahoo attempted to become a content company rather than a data company, as Google is. They made a lot of mistakes, going entirely in the wrong direction, in my opinion.

This business is all about sending traffic to the most valuable source. Google understands that. Yahoo didn’t, or doesn’t. The question now, will Microsoft?
