At long last, I've sat down for an afternoon (and an evening, truth be told) and implemented a discussion feature -- which I've called "heckling" -- for the site.

It's basic. Logged-in users can add a comment to any sentence, and all the comments from all the users are shown in order after the sentence on the page. And that's about it. There's no threading, no email notification, just the absolute bare bones of a system. But it's a start, and we'll see how it evolves from here.

At the moment, spam protection is being provided by the very worthy reCAPTCHA project. That may change, though. If I get too many bottom-feeding spammy morons attacking the site, I'll just go for manual approval of everything that's submitted...

Bearing in mind I've been meaning to do this for months and months, it's nice to have finally got around to it. Hurrah! I'm going to go and have a self-congratulatory coffee.
