Same here I just checked and found most of my site link popularity according to Google are "decreased". The link seems update for 2 times within 2 weeks. I bet something bis is going on. As I stated in another thread that last PR update is only minor experiment from Google side.
This is only my opinion based on my experiences. You should not count them as a fact. If you did observe through the threads in Google section on DP at the date that Google PR updated. You would noticed many of the threads express about the surprise of their increased PR. The last PR update was too sudden and many sites got unexpected amount of PR. Many of sites which new and have a few backlinks according to Google link: operator got PR2-3 easily. I didn't mean those site should not deserve it. But the recent PR update look strange. It looks like Google trying to change the correlation fact on SEO such as - Number of pagerank is solely based on number of backlinks. It seems not true these days. A Google pagerank algo changed. It is involed with many factors, including domain age, site content and rapidly of the acquired links. - High link popularity does not mean domination on every desired keywords. It seems that many old and established sites still got weight to have inner pages ranked for every keywords but now Google is trying to change this momentum. It just a feeling based on search for many keywords and not a fact back up on this.
