I run a small website that hosts wire feeds (AP, Reuters, etc.). When a reader asked for comments, I originally said no b/c building my own infrastructure + spam protection would take way too much time. I heard about Disqus and I literally had comments on every single news article in 5 minutes. This in turn created a forum. Now, I saw little usage of comments and took them down, however, the ease of use was incredible. Basically, if you have a website with content that isn't built on blogging software, Disqus (or InstantDebate) is a quick and easy way to implement comments.
