Long, long ago, in the dark backward and abysm of time, I added a blogroll from blogrolling.com. That sidebar to the right. At the time this was a rather cutting edge thing to do, and I was one of the cool kids. For months, however, my blogroll has been frozen in space: the blogrolling team protests weakly, every so often, that they're working on it, but one starts to lose heart after the third "we're almost ready!" update followed by a couple weeks' silence.
So I have been unable to add Clumps and Voids, Peony Moon, Northern Wall, Box Elder, and Ouroboros to my sidebar. Probably others too that are escaping my sieve-like brain at the moment.
I'm not a patient man. If this goes on another six months -- I swear, I may do something about it!
