I have been pondering myself how to grow and allow Steem to adapt to different age groups and insights. Currently it is about the first ones that were here and slowwwwllyyy migrating to quality of content and quality people. The only worry is that the quality people leave before the content catches up.
Yeah, I see what you mean by that, but I'm pretty sure that's where reputation comes in.
If you just spam post, then your reputation will go down. At least that's my understanding of it. Plus i think it's better to have quality, in which, their creators aren't just here to make money off of their work, but to help build this community. But again, I do see where you're coming from.
On another note honestly I don't think it would be that hard. Just make a teen (responsible that is) rich off of this platform and they'll make national and eventually international fame. Once, they talk about it, we'll get an influx of teens, but after a while only the serious ones will stay. And then off of them you use their relationships to build the platform. Or at least, that's what a perfect scenario would end up like.
