So lately I've been playing with twitter. It seems like a fun toy, but all that visiting the website was getting tedious.
I took the obvious action, and wrote a small python script to let you post from the command line, much in the way of /usr/bin/mail. To use, download to a machine with python, and edit the username and password in the script.
It may even work for people who aren't me. One day I might tart it up enough for a formal release.
