disqus.com??--Good Links or Bad?

I was just curious if anyone knows if the Javascript on the linking system that http://disqus.com/ sets up is good or bad. Do you get all the PR from the link, some, or none? It doesn't seem to create a nofollow tag, but, thought we might not be getting the best quality links.

Below is an example of the blog commenting style that disqus uses.

Thanks for any input. I"m kinda new to this.

Oops, here is the good link.

I think they are useless since they do not apear on page source.
