No wonder my rankings tanked. My sitewide from Facebook lost PR. Looks like I need to replace it with a sitewide from twitter. As always, great post JCash!
There's some critical bugs in the pagerank algorithm and a pr update needs to take place immediately. I looked at this twitter.com and it appears to be just a squeeze page for some sort of membership site. How can it be outranked google?
Actually it looks like twitter is also engaged in some sort of scheme to game pagerank with their t.co domain, when you load any t.co url as googlebot it issues a redirect to twitter.com
