I think you just click on their photo in the 'followers' on the left, then click on their links. Some have more than one.
But many times when you click on their photos, all you get is a link to send them a message--does that mean they do not have a blog?
I think that unless they add their link to their box you can't find their blog, which is rather annoying.
Hey, I was able to Comment on your blog, Warped Perception!!!! But can't seem to get to Martin's blog... Martin, if you see this, can you leave a comment with your URL for your blog?
