“Twitter is like an RSS feed to every boring aspect of your friend’s lives. And your friends are boring. How could they not be?” So writes Helen A.S. Popkin on MSNBC in one of many scathing reviews of the micro-blogging tool Twitter. Twitter lets you update other friends in your social network about your whereabouts on a micro-level from your cell phone via text messaging or through instant messaging or the web. Ever since the recent South by Southwest conference, usage for Twitter has been doubling every three weeks, according to the service’s founders, though they wouldn’t provide exact numbers.
