I think it's upto each user to find the right balance for them and their followers.

Sometimes I unfollow people who resteem low quality posts into my feed. As my feed is the main way I browse content on here. It also works the other way too, if a user is resteeming posts I like, I will follow them as they are curating posts that I would not have otherwise seen.

But it's definitely worth experimenting with for most users. As at the moment people are paying for resteem bots to get more exposure. If the community resteemed good posts, it would make it much easier to get more votes, which ties into your steem uprising strategy!
