Reply to Is online radio going to work for promotion in 2013?

Hello Tech Tools Djs.

My question for all of you: is it worth to start an online radio in 2013 with all the alternatives for promotion and engaging with others that are out there, mostly social (ex. soundcloud, mixcloud, etc.)
I see online radios like frisky, Proton, Digitally Imported are still here (well, they are because they're at the top).

What do you believe?
