Mixlr

Haven't used it myself, but I can see the use case for it...

Mixlr's been around a few years but has stayed relatively under the radar. It's well designed but not sure it has the audience to attract content creators and at the end of the day, the quality of content is what matters most. This challenge is further amplified because it's real-time. Do you use it, @ediggs?

For live broadcasting, I've used NiceCast - https://www.rogueamoeba.com/nice... (an IceCast client) - which is Mac desktop only, much more complicated to use, and much more powerful. I think the challenge for Mixlr to gain traction is that if you're going to all the trouble of making a high-quality audio stream and promoting it enough to find a real audience, you might as well invest a very small amount of extra money and effort to use a more professional broadcasting tool.
