I do not understand The Twitter.
I finally caved under pressure and signed up yesterday, hoping to use it as a marketing tool for my patterns and writing. So far I've posted five times and have four followers. I would have had more...except I seem to be a porn magnet. I keep getting followers with profiles that are empty except for a link, which inevitably leads to a porn site.
I think that from now on, I will simply ignore my followers.
If you are a real person and would like to see what I'm tweeting about (mostly knitting and snow at this point) my username is @KnotMagick.
