I'm not a huge fan of delegated stake either. People delegate their stake away, then post, and act confused, wondering why nobody with stake is voting. It's their own damn fault. That's the choice people make and when several do it, causes a negative feedback loop. They sacrifice post rewards on their work for post rewards stemming from the work of others without having to actually look at it. They get paid to look away, and others get paid to not look at theirs. Again, that's the choice they made. If they don't want that, they can stop. No need to makes rules. Common sense might kick in eventually but until then that's what they get. You had mentioned allowing network effect to freely do its thing, and that's one of the results.
