Oh no no no no no...Google was an algo beta invite webmaster driven test!
It was probably the first viral, correct me if I am wrong, mass promotional testing ground...I was there, I was heavily involved in what happened.
Bing is not doing the same thing, they are keeping it "in-house" whereas Google basically "let it go wild" and watched what happened as testers chucked loads of crap at it and watched the consequences and then refined them.
It was a pro-active playground for some of us who understood what they were trying to achieve and far superior to anything else on offer.
Google is still the intelligent bully of the playground for the moment, Bing has some serious flaws that it needs to address.
One subject no one has addressed is that of AdSense...many advertisers are comfortable with Google...errr...what are Bing's and Yahoo's alternatives for PUBLISHERS outside of the USA/Canada?
If there is a a solution, please post.
