The webcam streaming era(Justin.tv/Blogtv.com/Ustrem.tv/Any other simmilar service)

Well I never actually wanted to start a post about this, but here it goes. Basically what I want to talk today about is the webcame live streaming sites. Well some of us already use them to live stream whetever is for fun or business purposes, the other us know of them but don't use any, and the rest of us either don't know about them or don't care. These types of sites tend to make streaming easier for at least the medium user if not the average one, by adding certain features, like chat rooms, offline sildeshows and other little things. Well you may wonder which service to choose if you want to get into this activity? Since I don't know too much of these services, I'd say most of the offer almost the same features(with few new added) features like free account, chat room and other little stuffs. Since a list won't do any help here(depending on you're needs you may need the x service or y service) I say the best way is to compare them. If I'll have time I'll try to make a list in the future, until than that's all for today.
