I love Disqus

I really like having all my comments on various sites in one place. It makes following discussions really easy. I have added Disqus comments on this blog as well, not that I get much in the way of commenters at this time. As a webmaster I particularly love the Twitter and Facebook integration, making it easy for anyone to comment without having to allow unregistered commenters (which I currently do since this blog has such minute traffic).
