www.allwebdirectory.com seems to be a PR0? Also its 1.php's don't seem to be in the index (well at least not very many of them). When did this all happen. Have I been asleep?
I don't see how a BL update would make a difference on home page PR. SEO Chat PR tools is showing PR0 on all datacenters. http://www.seochat.com/?go=1&option=com_seotools&tool=9&url=http://www.allwebdirectory.com
Because backlinks have been bouncing around and PR values have been bouncing around in an odd and unpredictable way for at least a few days now... ignore it until the dust settles... you'll live longer.
minstrel: Ok perhaps I am over reacting. I know on a number of my sites the PR had been bouncing around also. And there is the issue of /1.php not being in the Google index (or not very many of them). Lets see what happens.
The fact the homepage is not cached any longer has always been an experience of dread... I have had two sites that were dropped from being cached and they took forever to get back and have never regained what was lost. One was a duplicate content issue and the other I still have NO IDEA. I don't ask anymore. I just go about my business and make sure I follow all the rules I can.
