It’s only a matter of time before people start to Twitter in the bathroom. If you don’t know what Twitter is (either because you don’t follow online technology or you’ve been locked in a sock drawer), that IS as bad is it sounds, but not in the way you probably think.
If you do follow online technology, you know that Twitter is the anywhere, anytime, instant publishing solution that lowers the threshold for publishing about yourself several orders of magnitude below blogging, such that there is nothing you can possibly be doing that is too mundane, private, or uninteresting that it isn’t worth posting on Twitter. Use of Twitter recently exploded in the geekosphere at the SXSW conference, leading to much pontificating on the existential meaning of Twitter, i.e. I Twitter, therefore I am.
I think Twitter is a well-executed application, which, like all technologies, is only good or bad in how it is used. What strikes me about Twitter is that it appears to be accentuating the natural exhibitionist and voyeuristic tendencies of avid blog writers and readers. While blog posts have traditionally been short, Twitter pushes this trend to the extreme, accentuating the attention deficit disorder that the web naturally fosters.
