Time to experiment on you all. I have installed a very alpha version of the plugin for Movable Type I have been working on for fourteen months (that’s what copious spare time does for you). I have the framework half way built, enough to put in a few of the features I want. What the plugin does is provide access to recent commments in various useful ways. I am using it on the right sidebar to display recent comments on this weblog grouped by entry. The old style just listed the comments in chronological order, so it was more difficult to see if a post you were interested in had new comments. Now you can tell at a glance if that’s so. Currently it lists all comments for the last two weeks.
I plan on using it for a comment feed in the future, but it needs just a few more features. Yes, definitely, it needs them. They’re not just gratuitous. Not at all. And they’ll be done Real Soon Now™.
