Blog with comments sections

Hi,

Does anyone know a stack or add on I can use for my blog so people can leave comments.

A sign in option (twitter, Facebook etc) would be preferable but not essential.

You can have comments with Joe’s Tumblr stack.

Disqus works really well. I don’t know what type of blog page you have. I believe the default RW blog page does integrate with Disqus. Other options, such as Armadillo blogs, also nicely integrate with Disqus.
