Is Microblogging all it’s cracked up to be?

You might’ve noticed that one of the widgets in the sidebar is missing.
Twitter has been an interesting experiment, especially some of the exchanges I’ve had with Sam Harrelson, who’s certainly an intelligent and expressive microblogger.
So what’s my opinion of microblogging?
It’s great if you’re at the sidelines of a seminar or tradeshow and a good way to get updates out. We might see some interesting updates from the Blog Haus at Affiliate Summit.
If you’re waiting in transit at the airport, or on a long subway ride, it’s a good time killer [Although I think you’d get more out of a good book…]
Where microblogging doesn’t work for me, is blogging in the midst of work.
If you disrupt your usual work to file a 140 character update, it can mess up your train of thought.
So though I’ll be checking in regularly to my twitter account, I likely won’t be checking it fantatically.
What’s your experience with microblogging?
