If you're looking to start a live stream, you're most likely considering either Justin.tv or Ustream.tv to stream on. I get asked all the time which is better… so here is my comparison of the two

Above all, I prefer uStream, even after the hellish customer support process. But, look at my comparisons and decide for yourself.

 

Ustream	Justin
Higher quality streams	Lower quality, less reliable
Better broadcaster built in	Unreliable broadcaster, but you can use FME
Bad customer support	Good customer support
Great community	Trollish community, but can be good on some nights
Featured list	"Producer" list
Geared toward professional type shows	More social atmosphere
IRC client friendly	White-listing process, hard to connect with mIRC/Colloquy
