Gut feeling
Its nice to see some people are not so giddy over the
new attribute that we can add to
links. I've heard people lauding this as the end of comment spam, and I
agree that it will be a big help, however, one important way that people
get "known" in the blog world is by getting moved up in the Google rank through
meaningful comments. I like the fact that when I make a comment, its
contributing to the conversation, but that I'm also getting a link to my blog
out there. Now, when I leave comments, it won't be counted if the blog
owner applies this attribute to all incoming comments.
This was my first impression when I first learned of the
tag, and maybe I'm way off base, but this is just my knee jerk
reaction.
