'rel=nofollow'in their comments, which has been originally proposed by Google as a means of curbing comment spam.
However, the tag has largely fallen short of it's intended effect in deterring spammers, the job taken over largely by Captchas and spam detection software these days, while leaving legitimate users less inclined to comment, after not being to benefit from the increased link count that is important for search engines in spidering your site.
Randa Clay started the 'I Follow' Movement in countering the usage of the
'nofollow'tag used in the comment links. As a fellow supporter being more open, I think it is a great idea, besides the fact it will be great motivator for others to leave a comment on my page as well.
Everybody benefits, I'll get more exposure, while you get rewarded with a link whenever you leave a comment. I've turned off my
'nofollow'link now, and if I've managed to convince you that it is a good idea, be a part of this and join the movement!
