Understanding the REL="NOFOLLOW" Tag

Especially within Blog Marketing

[nzap]

Hi,

Hoping someone can help me understand this better.
I know that rel=nofollow when placed after a link in html will tell google not to count that link towards pagerank or even index it.

But I'm noticing that a lot of blog sites such as the ones that have .blogspot domains have the rel=nofollow within the very bottom of their source code in a very long script that I don't quite understand, using something called "widgetmanager" or something along those lines.

Does this mean that this blog will block all links from being followed within the content or is this particular script only for the comments area. I notice the actual content links do not have the rel="nofollow" code. Just the very bottom of the entire page.

Will it benefit me to post my link on this and other similar blogs?

Thank you to anyone who can help me understand this more fully!

rel = "nofollow" tag have only and only one work that stop crawler to follow the links and thats why these types of links are not counted as backlinks in SEO.

Thanks
