JohnChow.com is showing up as a PR3 in many data centers, down another point from the PR4 he was earlier this month. JohnChow.com was a PR6 site about five months ago. This shouldn’t surprise anyone because John continues to sell advertising that passes PageRank. John doesn’t care anymore because his blog is already very popular.
John's already making too much money off his blog relative to the crap he actually posts, he probably doesn't give a hoot about Pagerank at this point
As long as the site is still getting a high amount of traffic, I doubt this drop in PR will cause much affect.
