Well, it’s the beginning of the new year and the beginning of the next quarter. So, this typically means that a Google PR update is imminent. By all accounts, right now, though, all looks quite on the Google-front.
On a separate note, it appears that the Big Daddy update at Google / AOL has also not taken place yet, though there are some indications that the AOL SERP’s have been bouncing around lately, so this may just be a minor update. Also, Matt Cutts from Google has mentioned that his company is testing out a new datacenter, which is actually the Big Daddy update (Big Daddy is not an algorithm change but a foundational change).
The Big Daddy datacenter is supposed to address canonicalization of URL’s and 302 redirects, which have caused numerous headaches to webmasters over the years.
Good luck on high rankings.
