A lot of bloggers might have asked themselves this very question this week, when Google decided to change their algorithm and make it even harder for sites to have a good PR. I could start telling you why it has all happened, but I'd rather let an expert have a say on this topic.

Mihaela Lica (Mig) has written a comprehensive article on this subject on one of her blogs, Pamil Visions Tutorials. Go ahead and read it, it will surely make things a lot clearer for you. And take her word on this subject: PR is not that important! Take my case, Google PR is dropping while Alexa ranking are improving on both of my blogs.
