Stick around to the end for this one, it gets pretty funny.

I can see how people would think this about Twitter.  The beauty of it is that, deep down inside, we're all a little bit weird. We obsess over our interests, and realize that in normal converstion that we'd never really get to share those interests with others, because... who really cares? But that's really the beauty of Twitter. You just share what's on your mind and if someone else cares, they'll say something, if not, they won't.

I think it really works for those of us who are a bit introverted.

That said, one of the few things I got out of the Economics class I had to take in college was the law of diminishing returns, which basically states that as you invest more and more, you begin yielding less and less from your investment.

I think that eventually we're going to find that applies to Twitter as well. As everyone you know starts using it, it becomes less and less useful. Much like Facebook and all those ridiculous SuperPoke, MafiaWars, etc. notifications that we all constantly get.

Twitter may become a victim of its own success, in record time.
