Oh! People have been posting comments on my LJ feed! I really had no idea, although I’d known it was possible. I guess I’ll have to look at that more often.
The new (well, most recent) version of NewsBruiser has native comment capability, actually, but even when I do get around to upgrading I don’t think I’ll turn it on. It just doesn’t appeal to me. I do like this system, though: anybody who wants can comment, so it’s fun, but they don’t show up on the main page and they disappear twenty-five entries later. Comments are pretty ephemeral in nature–I think Frank Lloyd Wright would approve.
