Twitter.com vs. live video from Justin.tv

Okay, so what is Justin.tv and what is twitter?

http://www.Justin.tv is…

The place to broadcast and watch live video online while chatting with friends.

http://www.twitter.com is…

a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?

Both sides are geared towards lifecasting.  Although most people think of lifecasting using video, minute events that make up your day to day life can be broadcasted however you’d like.

Truthfully, I prefer twitter over Justin.tv (and I know people are going to say that these two applications are meant for completely different purposes) because of timing.  With Justin.tv you see it as it happens, so you are wasting your time, watching someone else…sometimes doing nothing.  Plus, you get a lot of unsavory people on Justin.tv where on twitter, you can keep up with people you choose, when you choose, and only see what they want you to see.

I guess I don’t get the point of Justin.tv, some people just point their cameras at a TV and re-broadcast TV.  I’ll stick with my sling box.  Are there any Justin.tv users out there?  If so, I’d love to hear what benefit you get out of it.
