How do you find a good list of blogs that don't use the nofollow tag?
Type in "blogs that do follow" in Google and you'll be surprised to find out how others advocate and listed hundreds of blogs that hated the "nofollow" attribute.
I heard a rumor that Yahoo has been ignoring the NOFOLLOW tag for some links. Not sure how true that is but it is always good to know if a blog comment or signature link is going to be followed by the Search Engines.
There is a free plugin for Firefox that highlights NOFOLLOW links on a page so you can see if blog comments, signature links etc are going to be useful for a particular site.
I can't think of the name of the plugin right now but I'm sure if you search you will find it!
Great begginer tips. But in the long run you'll find out that you'll need extra creativity to build links out of nothing. That is, of course, a good thing.
