Have you heard of the Do Follow movement? It is buzzing all around the blogosphere like crazy!
Bloggers everywhere are adjusting their blogs to either add the dofollow plugin, like on Wordpress, or taking some code out, like in Blogger - in order to make their blogs Do Follow-Friendly!
You can read all about it at Randa Clay's blog and also get yourself a button to proudly display on your blog to let your readers know that their comments count! The buttons come in lots of colors to match your blog!
