Twitter’s usefulness explained by David Carr

Columnist David Carr on Twitter:

What could anyone possibly find useful in this cacophony of short-burst communication?

Well, that depends on whom you ask, but more importantly whom you follow. On Twitter, anyone may follow anyone, but there is very little expectation of reciprocity. By carefully curating the people you follow, Twitter becomes an always-on data stream from really bright people in their respective fields, whose tweets are often full of links to incredibly vital, timely information.

The most frequent objection to Twitter is a predictable one: “I don’t need to know someone is eating a donut right now.” But if that someone is a serious user of Twitter, she or he might actually be eating the curmudgeon’s lunch, racing ahead with a clear, up-to-the-second picture of an increasingly connected, busy world. The service has obvious utility for a journalist, but no matter what business you are in, imagine knowing what the thought leaders in your industry were reading and considering. And beyond following specific individuals, Twitter hash tags allow you to go deep into interests and obsession: #rollerderby, #physics, #puppets and #Avatar, to name just a few of many thousands.
