Invariably, when I speak to someone who doesn't use Twitter, I hear the same thing, "Why do I want to know what someone had for lunch?" It's hard to explain why this might actually be interesting, and how Twitter is for much more than that. But admittedly, the service is immature and still stuck with lots of ephemera of people waiting at airports and "plowing through email." The platform will succeed when it gets more mainstream entities building useful services. BakerTweet is a small example of this, so too is what the food trucks and Naked Pizza are doing. Comcast and others have proven how it can improve customer service. Thanks to a tweet from @bigspaceship, I came across the MTA's feeds for subway lines. Nothing is more frustrating for NYC residents than not knowing what the hell is going on in the subways. I'm already following my main line. Now, hopefully, I'll know when construction means the 2/3 is running local to Chambers, which it does about every other weekend. Twitter is not the Second Coming, but it isn't Second Life either. The trick will be if more companies and organizations use the platform to provide useful services.
