Toolbar PageRank hasn't been updated in years, and now it will be completely removed. According to a piece in SEL, "that means that if you are using a tool or a browser that shows you PageRank data from Google, within the next couple weeks it will begin not to show any data at all." Of course, Google says they still use PR data internally - but no longer will it be available in any way, shape, or form to the public.
"Ever gotten a crappy email asking for links? Blame PageRank. Ever had garbage comments with link drops? Blame PageRank." I really have to agree with him. It was great - and generous - of Google to be open about how they rank pages on the web. Unfortunately, SEOs became so single-minded and focused on PR that it created a disastrous, manipulative whirlwind of spam and garbage. Like Sullivan, I doubt this will make the garbage-tornado go away any time soon. "PageRank scores launched the link economy, but that economy long left the actual scores behind." Ah well...better late than never I suppose.
