It appears google has throw us for a loop again. My Google pagerank (PR) for my website has dropped from 3 to 2 already down from 4 previously this year.
Although PR may not have a direct influence on traffic to your site it does affect how you could possibly show up in search engine.
Well from what I have just researched it appears blogging may be the culprit. No sure why but if anyone else has more information on this I would love to hear about it.
Here is what some wrote in a post about it

As a resident voice on SEO, I can't help but weigh in on this one.
My working theory isn't that all of these sites have necessarily been penalized, especially considering many of them are doing nothing wrong. Rather, I believe that the sites linking to them have been largely devalued.
Consider this: The primary audience for many of these sites are bloggers. These sites derive their popularity from others who are quite likely being penalized. Now that the algorithm has been changed and all those links have lost their juice, the popular blogging niche sites are losing PageRank as a byproduct. It's regrettable, but largely unavoidable.
I'll keep everyone apprised if I come across a better explanation, but that's the best I've got for now. Honestly, it's a bit of a head-scratcher, but this is why it's never advisable to put all your eggs into the Google basket.

I don't want to stop blogging just b/c of the Google King!!!
