Justin.tv

Justin.tv is a great website that allows you to broadcast yourself (or anything you want to stream through your computer). It is incredibly easy to use. All you need is a computer, a webcam, and a microphone (my laptop has a webcam and microphone built in). By going to justin.tv and signing up for an account, you can create your own internet channel. I find this incredibly useful for doing a live presentation. You could give a presentation from anywhere in the world. Justin.tv also gives you the ability to stream video files from your computer, so you could do a viewing of a video that you created. On your channel's page, you can set times for your broadcasts to let people know when to check back to watch you. You can also set up a chat function to allow people watching your channel to chat with each other and to allow you to chat with them as well. You could also have people text you a question that you answered live.
