Some of the sites I create are to provide information, share knowledge and don’t always require the ability for people to post comments and feedback. Also sometimes you want comments on posts, but not on the pages that may contain them, or give other information. This plugin is brilliant for just that need. You can have comments disabled across the whole site with just a click or two, or just enabled for posts or most other combinations. This saves having to remember to change the default for each post one way, or the other.

Anything plugin that I install, by default, and nearly always find myself using, mainly to allow comments on posts, but not on pages, media and categories.
