Twitter Meaningless?

In an article for TechCrunch (http://www.techcrunch.com/2009/08/17/why-i-dont-use-twitter/), Devin Coldewey lists the reasons for why he doesn’t use Twitter. “Tweets have no value” he suggests, and continues to say that a tweet is “a quantity of data which I believe to be useless, at least in this context. What can be said in 140 characters is either trivial or abridged; in the first case it would be better not to say it at all, and in the second case it would be better to give it the space it deserves.”
