Grumble Flap Housekeeping

I am in the process of reviewing (and lightly editing–typos and formatting) old posts. This blog contains posts from a couple of previous blogs originally hosted on Blogger. (They were called Interstellar Gas and This is Worker, for what it’s worth.) I am also adjusting the categories into a smaller number of topics.

As a result a number of old posts are being automatically fed to Twitter at a remarkable pace.
