Is Twitter lost on me?
msb: I was having this discussion with a friend last night...Like you, I have struggled to find personal relevance with the social aspects of the service.  My friend pointed out to me that the recent mainstream growth that Twitter has been going through is starting to create a lot of services that lay outside the two demographics you mention. The one that I found most interesting was local businesses (movie theaters, coffee shops, restaurants) tweeting about day only or hour only specials etc.If you start to think about the Twitter service outside the bounds of social networking there is a lot of potential value that is just starting to be discovered.
