That's my point. Technology has advanced dramatically since the 60s and 70s. You used to need huge teams of highly-skilled technicians just to handle the mechanics of editing, lighting, sound-recording, special effects, etc. Now you need: iMovie and a cell phone. That's allowed small groups of college students to put out creative works on par with what a major studio could do 40 years ago.

Or to tie it back to the Facebook example that started this thread: I regularly have political discussions with my friends on Facebook (or with folks here on HN, for that matter). If I say something interesting, there's the chance for that to go viral through reshares. When I was a kid, my favorite part of the newspaper was the Op-Ed section, and I always wondered what you had to do to get featured in the Op-Eds. Now everybody has their own personal Op-Ed section, with their own audience, and the type of discourse that was previously reserved for institutionalized publications now happens routinely on the Internet.

It's just that standards have risen correspondingly, so instead of this seeming amazing, it just seems like everybody is shooting their mouth off. Which it is, of course, but people fail to realize just how huge an achievement everybody being able to shoot their mouth off is.
