Disqus

I'm in the middle of installing Disqus on my blog for comments.  I'm wondering if anyone has used this on their blog and how they like it.  I'm trying to understand all that is required of it so I don't know if it's working yet.  So leave me a comment and we'll give 'er a good ol' test run and see how like it mmmkay. 
Thanks!
PS:  Is it lame that I only just realized that it is most likely pronounced "discuss" and not "disk" like I've been calling it?  Yes people, I'm quick on the uptake.  Now go forth and comment.  I need your help!
