There’s a new Comments feature for Radio Userland. This is basic, but very cute and very easy to use. I’ve enabled it as an experiment. Now, if you should so desire, you can leave comments on Status-Q!
I don’t think, in this incarnation, that it’s obvious when people have done so. That’s not quite so easy to implement especially when, as on this site, the main pages live on one server (mine) and the comments on another (Userland’s). Fixing that could be a real test of Web Services!
