Yo SIF!! ;)
 
I am liking the new system! 'Course...I think we could dream up a better one, dontcha think?!
 
I've never used Disqus as an "owner"...I could never get beyond attempting to install it...I kept getting weird messages about deleting my widgets!
 
Panic!!
 
So, Intense Debate...I have had NO trouble with them...but I know of a few that have. I LOVE the reply option. I hate that people hafta "do extra stuff" to log in...but I know it could be avoided if they signed up for an account.
 
My verdict...I like the change...not in LOVE but definitely in like! I would say go for it! I think it is a way better option than the standard Blogger system!
