Well I did it. I broke down and have joined Twitter.

Username: KWF

And I got the Terminal updater to work. Here it is if you want to use it:

~/bin/t

#!/bin/sh
curl -u user:password -d status="$1"\
https://twitter.com/statuses/update.xml -k

Usage:

t "This is a new message"

The response will be Twitter confirming that you message got posted in XML. Now the real question is: How do I see everyone else’s twits from the command line?
