This means that Blogger's relatively anemic commenting system gets gutted and replaced with a shiny new toy that allows threaded discussion and a bunch of other goodies. It seems to be working just fine, so take it for a spin and let us know what you think. You do not need to sign up for any services (even OpenID) to leave comments. Signing up for Disqus will allow you to edit your posts and interact with other commenters on many sites that use it though.
