I don't like how you can't reply under people's comments on blogger so my friend told me about Intense Debate and I've used DISQUS in the past with tumblr. They both do the same thing and since I already had an account with DISQUS I just stuck with it. Only thing I don't like is how it gets rid of all your old comments when you install DISQUS. Oh wellz!
Anyone else use either one and how do you like it?
