It seems that Twitter has really gone mainstream. The March 16 issue of the Wall Street Journal contained an article about Twitter. One of the Twitterers interviewed had the same response that I did when I first heard about it: "I didn't get it at first." But once you try it, it's Twitdicting.
But more than being simply a waste of time, there are some business applications here. At a party tonight (ironically with a 1920s/30s theme), I introduced Twitter to a couple of people. One could immediately see a use with his geographically-dispersed sales team. Unlikely to check email often, the team is all about their mobile phones, and Twitter is perfectly suited to that channel.
Steve Rubel tweets that many good business ideas will emerge via Twitter. Certainly. Beyond ideas, what about actual business uses of Twitter? Web Worker Daily has 8 ways Twitter is useful professional. Personally, I'm using it to do some networking for a social media job search.
We'll probably see more selectivity and thinning of friends on Twitter as people begin to get tired of hearing what someone is planning for dinner or when they're picking up the kids from little league practice. Twitter has its use for the social set, but those who are using Twitter as part of their business - like the Twitter feed set up by Bryan Person - will quickly fine-tune it to their liking.
Props to Dave Armano for the Twitter link to the WSJ article.
