"In the end, my impression of Twitter was right and wrong. Twitter IS a massive time drain. It IS yet another way to procrastinate, to make the hours fly by without getting work done, to battle for online status and massage your own ego.

No other communications channel can match its capacity for real-time, person-to-person broadcasting." Source: From the Desk of David Pogue - Twittering Tips for Beginners - NYTimes.com
