Google updated my PR1 to PR2 only. I suspect that some sites have broken the link exchange. I’ll have to check that when I have the time.
Anyway there is one good thing, almost all pages have a PR now, including all link pages.
There is something I don’t understand though. I have internal pages with higher PR than the frontpage.
By other side, if there is a PR in Yahoo, I’m certain it is much higher than in google since I have very good rankings on first page for certain competitive keywords, competing with long established respected sites. This is not a surprise for me since my site is a complex portal and is not targeting a very specific topic or keyword. As long as I know, a site with only a few pages and targeting a very specific topic has more chances in google in the short-run. That is not the case in Yahoo and MSN, and was my option from the very beginning.
For now I’m happy with it.
