There have been quite a few people bashing Twitter over the past few months. While I do find that the “public” time-line traffic is mostly a bunch of garbage, I think many people are missing one of the major points of Twitter. Within a “real life” social network, Twitter can be a very useful tool to coordinate and mass update people in a group. Friends can form a network within Twitter (by subscribing to eachother) and subscribe to SMS updates via their cell phones. If a group is networked via Twitter the members may send updates to the entire network via their cell phones. This feature can come in handy when making plans that involve large groups of people. Having an SMS conversation to coordinate groups of people becomes very easy.
