Google Dance is not finished

I put attention that many sites with high Page Rank lost from 1 till 3 points in their Page Rank during last week

New Google Update

You can see new results if you change IP in your hosts file here
C:\WINDOWS\system32\drivers\etc

127.0.0.1 localhost
209.85.139.104 toolbarqueries.google.com

Wordpress admin changing

For my opinion admin changing in the wordpress are not so comfortable
If you have multiple blogs set on one account now you links to them on the top horizontal menu and you don't see at all of then and so you don't have an access to everyone of them.
Also you don't have a link to blogroll or statistic info from the first screen as it was before.

Buying links

Check following parameters
1. Google cache date
If it's more than 2 weeks - not so good
2.Number of backlinks
3.Number of Google indexed pages
4.If the inner pages have some page rank
5.Age of site
6.If you buy multiple links preferable to buy from different IP
