Think you missed reading some cool comments? Check out |100 Comments| in the top menu.
It lists the last 100 comments on the site, which lately is just over two days worth. :) You can sort the comments by date or by title, and look at just today's or just yesterdays. None of the other sorts on the menus work, sorry.
This will be comments on all posts, including stories, blogs, forums and polls. Have fun. :)
