Some great observations by on the state of the following 6 changes that we kind of expected for a long time, but never really seemed to come about.
1. Has to do with topical PageRank which I do believe Google is using as Matt Cutts mentioned in a video a few weeks ago. But as Rand points out, there are bigger factors for Google to consider overall as to what makes a page popular with users. Topical links may just not be as important as we thought & the algorithm is just not a simplistic as many believed it would be (ie. tech = tech).
2. Anchor text has always been a core concept & apparently it's not that easy to get rid of.
3. Temporary redirects are seldom temporary.
4. Canonical is more powerful than Google would have you believe, be careful how you use it.
5. Twitter, Facebook, splish-splash-sputter.
6. There is still a surprisingly enormous volume of totally obvious web spam & especially in the traditional bastion of the web spam industry porn-pills-casinos. Matt keeps talking about bigger, stronger clean-ups, you can be sure this is not over yet.
