Interesting point of view on why Twitter may not be long for this world. I would disagree with most of the sentiment which appears to be from someone who does not “get” the service. If you find it overwhelming and you just see what people are eating – you are following the wrong people. Twitter much like Facebook has its idiots and mass-marketers. There are however a select few(thousand) who post insightful and truly interesting stuff daily.
Twitter may be a short term service, but it is not worthless. There are a lot of good points here, but try to ignore the naive slant making Twitter sound like a useless service – it is unfounded.
