I can speak directly to this. I recently started making electronic music of my own, and have been building a small community of fans and listeners. I don't want to give the wrong impression here (it's still friends and family and only a few strangers), but if SoundCloud goes down, it will basically destroy the progress I've made so far. I am a bit freaked out right now with this news. I really hope the torch gets passed and I don't have my community pulled out from underneath me.
