My upload speed is terrible so I can't really broadcast, and I am vehemently against Facebook and other social media. I'm hoping they'll touch up the option of saving it to your system to make a bit more clean in the future, and maybe add Youtube support. Can see myself using it quite a bit then.
At the very least, it is nice that it's bringing so many new streamers onto Twitch and Ustream. Once you navigate post the three dozen boring/bizarre Playroom live shows anyway.
