Tab Pierce, Director, Business Development at Security Innovation asks, over on LinkedIn: OK...so what's the big deal with Twitter? I've had several people talk to me about joining. Which I finally did, but what's the big deal? People posting what's going on in their lives. We do that here with updates, it's done on Facebook and Myspace too. Am I missing something? I love useful tools, so I'm hoping someone can provide me with that aha! moment so I get it.
