If you look into the navigation bar on the right you'll see a new section for Recent Comments. Right now it displays comments made on any entry in the past three days and puts the old colored-ball-of-updatedness next to it. I put the code together this evening so I'm sure there are bugs and/or features left to address. In the process the base code was updated to enable access to a single entry. Not that anyone should notice or care, just something I've been meaning to do for about a year. ":^)
Something to think about: most of my weblog entries don't have titles but I'm using the title for the recent comments hotlink label. I've started putting titles on new posts in anticipation of this feature, but to tell you the truth I don't like doing it. One option would be to have an invisible title, which ends up being used only for the comments thing. Or maybe I regex the text and pull out the first noun or two? What about pictures? It's tough enough to figure out ALT text for some of the pictures much less have the same text as a blazing, big font title. I guess I could move the title to the bottom of the post, in small, faint letters.
