In what was one of the more clumsily handled transitions in recent interwebz history, Haloscan was phased out and replaced by something called Echo. We had the option of taking Echo or...nothing! that is, losing all our old comments (they could be "exported" for import into some future theoretical commenting system by a means that didn't yet exist). Anyway I didn't act on this so my account got ported to Echo. And it sort of works, but for some reason the comments aren't showing up on the main page today. You can't get to them by clicking "comment" either, but you will if you click on the title of the post in question.
I'm hoping they will magically fix this but I suppose I need to go complain to someone...
Enjoy the game, those of you who are watching! (I will be)
ETA: Comments are back -- it seems to have been a widespread problem.
ETA 2: Oopsie. Comments are gone again. Sigh.
