It's surprising to me how most bloggers could care less about their domain name. It would drive me absolutely batty to have a number as the sole identifier of my weblog.
Yes, it bugs the hell out of me. The Radio weblog was just a bit of a weird hobby I never really expected anyone to read, but then one day I started getting links and readers, and I was somewhat stuck with it. Now I've got enough link-cred that Google notices what I'm saying, and that's a drug that's hard to give up.
I don't particularly like Radio either. I was planning to just stick MT or Roller on www.pastiche.org and be done with it, but then my hosting provider jacked up the prices by 33% and I had to move the server back onto the wrong side of my 56k modem.
Oh well, at least 190 is a low number.
