yep, backlinks have changed for me. For the worse unfortunately. 104 links have shrunk to 57. Discouraging after it took google the best part of a year to recognise I had any backlinks at all. Rankings seem unchanged though. They didnt change for me after the last PR update either.
On closer examination I seem to have suffered far less than my competitors - some of whom have dropped from 300-400 backlinks to only 3 or 4 backlinks. Google does seem to have removed a lot of obvious reciprocal links. I'll be very interested to see how this affects PR and backlinks.
Did someone say that you can check your PR on the different datacentres? How is that possible?
