On my main blog and site I've got the 'Add This' button, Twitter 'Follow Me' and Tweetmeme 'Tweet Me' button on every post and page, some in the sidebar and some in the footer.

Good, you might think, now your readers can bookmark you right up!

But looking at the code, all these buttons contain dofollow links to twitter, addthis and tweetememe. Am I inadvertantly watering down my Google PR and leaking link juice all over the carpet?

I've edited my follow me button to be rel=nofollow but before I go through the same task with the others I thought to ask your opinions.

What do you think?
