Paged comments plugin
So your blog is so popular that you regularly get hundreds of comments on your posts. This makes the pages on your blog incredibly long, forcing users to keep scrolling down if they want to see the comments.
Kevyan Minoukadeh’s WordPress Paged Comments Plugin allows paging for comments. This means that instead of one long page of comments, your comments are divided up into multiple pages. Kevyan says this is useful for popular blog entries or simple guestbook pages in WordPress. Installation seems to be pretty straightforward.
