I’ve been using Twitter both on my computer on my and phone for a while, but the user experience of the phone has been a bit rough. One option is to turn on text messages and be interrupted by your phone every time a friend Twitters. Another option was the use the standard web interface, which required lots of scrolling and painfully slow load times.
Twitter is one of those services that people either love, hate, or can’t see the point. I’m in the “love it” camp. It’s a great way to keep up with friends. I like knowing what new app or gadget Josh Bancroft or Chris Messina are testing. I also get great lunch suggestions from people like Raven Zachary. The best use of Twitter is at big events where you can learn which session, party, speaker, etc. really stinks and which ones are a must see. At sxsw, Chris Messina organized an OpenID meetup primarily over Twitter. News also spreads quickly via Twitter, and I frequently see breaking news on Twitter before other mainstream media sources. The best part is that you get this information quickly and easily from your community of friends, acquaintances, and coworkers.
