ReadWriteWeb.com has a handy post explaining how all this works. The process is rather cumbersome, as you have to add people one at a time to the lists you create. You also have the option to make your lists public, so that can create some very interesting lists for others to follow. Getting on certain public lists will probably be the next status symbol next to the number of followers.

Also, each list can be followed as well, which will probably touch of a new frenzy as lists are created and followed.

It will be fun to see how all this develops. In was inevitable that Twitter would start adding more features, but the simplicity of the service has been one of its best qualities. Simple often works better, though that often changes when you have explosive growth. It’s a great problem to have, so get ready for lists mania!
