More important though than "everyone can become a broadcaster" is that broadcasting means you have something to broadcast. Putting together a broadcast takes time. You say "not many people were aware of ____, so you didn't reach many people", but the flip side of that is that people who are aware of xyz broadcast medium and wish to broadcast something (thus providing more content for consumers of the broadcast building into a feedback loop of broadcast/consumer growth...like television) don't always have the time or energy to produce something decent for broadcast, or to produce something at all. How many completely dead Twitter accounts are there? Twitter's retention stats show that this is true even for something as completely cut down as Twitter (creating a broadcast requires mere seconds of time)...they only retain, what, about 10% of their users (or maybe rather 10% are active)?
