Hi, I'm the author of DigeratiMarketing. While I think it's ironic that there's only 1 comment here, I just wanted to point out a few things that have been overlooked..
For instance, "...wont nofollow them to be honest I only use them when linking out to a potential bad nieghbourhood. "
How do you know when you're linking to a bad neighbourhood then? Do you change you user-agent or referrer when checking the page that's being linked to? Do you inspect the information in the header? If not, then it would be quite simple for me to dupe you into linking anywhere I wished.
Just nofollow your comments and be safe, there are thousands of blogs with nofollow with great followings. Tbh, all user-generated content should be nofollowed.
