Twitter is just one decent take on real time pub-sub systems, which has been around for a while, previous incarnations include mailing lists, usenet groups and various forums etc. Twitter simplified the pub-sub of short messages from/to mobile devices and takes advantage of the aggregate knowledge. I think Twitter will be successful (profit!) in business marketing/networking, simply because it makes pub-sub simple. I personally will probably never create a twitter account to follow or be followed because I'm more comfortable being a private explorer/observer (reading thousands of feeds and commenting occasionally)
