Okay so a lot of blogs have decided to add dofollow plugins to allow visitors to express their opinion and actually get a link out of it. I decided to be one of them and even advertise my blog as a dofollow resource for links by listing on dofollow directories, and guess what happened 3 days after I did? My pagerank dropped from 3 to 2.
Take a look at this dofollow blog directory and see how many of these sites have lower pageranks than what is listed. Coincidence? Me thinks not. Is Google really penalizing sites for coming out of the closet as dofollow??
