Remember when there was the WordPress plugin for FriendFeed and how it imported your comments?
Well, it seems like there’s the same that goes for Movable Type. What’s neat about this is that it basically will repost the comments from FriendFeed directly into your blog as comments. This makes the conversation more worthwhile since you’re able to read transactions that not only happened on the blog, but on FF without having to go track it down on FF. Perhaps a fluke, but at the time that this plugin actually was installed, I noticed a tremendous shift in MySQL queries to the blog. Not sure if this happens with others, but I would definitely keep an eye on it and report it to the author (Mark Carey) if it still exists.
