When the site gets out of beta and Goes Big, it's only going to get worse.

Maybe Steemit needs some form of customizable filters so you could for instance filter out anyone with a Reputation below 42, or anyone who had posted more than 19 times in the last week, or anyone who was muted by 4 or more people you followed. You could set the filters how you wanted. I'm not a web developer, but from what I know about programming, I think things like that would be quite possible.
