The point of Twitter is to shout into the void. Anyone looking for a more interesting reason to use Twitter (and, arguably, any other 'social' website) is mad.

Actually, that's not true. Twitter is also good because it allows you to follow @Horse_ebooks, @DJsComplaining, and me. If you want to follow me, my handle is 'enlightenment' in Icelandic. It's also my handle on loads and loads of other websites, so feel free to follow/connect/whatever me on those as well.
