As with all things, some self-discipline is so important.
For sure. However, people are growing up with these things in their hands since before they could talk - they are conditioned to follow, not guide the self.
Hive has lots of crap - but that same crap doesn't get incentivized "that much" in comparison.
True! In theory, at least, the best content gets rewarded the most, so we are all incentivized to produce only great content. But of course there are so many factors, including writing skills (or lack thereof) and the subjective nature of it all!
