Twitter, a micro-blogging service where users post what they’re up to in 140 characters or less, once thought the province of the self-absorbed, has been growing drastically as friends, businesses, and even services like fire departments find ways to make “tweeting” work for them, the Wall Street Journal reports. The site says its user population has soared sevenfold over the past year.
Twitter.com had over a million unique US visitors in August 2008, from 282,000 in August ‘07. Doctors are using it for scheduling; Dell is using it to advertise deals; some get instant advice, both professional and personal, upon querying the site’s faithful. “Looking at the value commercial entities are getting out of Twitter could help us build a sustainable company,” says its founder.
