Another technology to play with. Joy.
I found this Wired Magazine coverage from last year very enlightening.
"Twitter is the app that everyone loves to hate. Odds are you've noticed people — probably much younger than you — manically using Twitter, a tool that lets you post brief updates about your everyday thoughts and activities to the Web via browser, cell phone, or IM. The messages are limited to 140 characters, so they lean toward pithy, haiku-like utterances. When I dropped by the main Twitter page, people had posted notes like "Doing lunch and picking up father-in-law from senior center." Or "Checking out Ghost Whisperer" or simply "Thinking I'm old." (Most users are between 18 and 27.)
It might seem like blogging taken to a supremely banal extreme. Productivity guru Tim Ferriss calls Twitter "pointless email on steroids." One Silicon Valley businessman I met complained that his staff had become Twitter-obsessed. "You can't say anything in such a short message," he said, baffled. "So why do it at all?"
They're precisely right: Individually, most Twitter messages are stupefyingly trivial. But the true value of Twitter — and the similarly mundane Dodgeball, a tool for reporting your real-time location to friends — is cumulative. The power is in the surprising effects that come from receiving thousands of pings from your posse. And this, as it turns out, suggests where the Web is heading."
So if I Twitter, will I seem young? ;o)
