The way this will be handled, in the future, is by something similar to a black list. You know your friends and those who post regularly. Even the ones who disagree. (good disagreers are hard to find) and so, you know who to white list.

The black list is hard, because currently it is viewed as system wide. But really, it should be more of a group level thing. Or, you subscribe to a friend/service that has the same outlook as you and has the time / takes the time to weed out the good from the bad.

As steemit grows, this will become even more necessary as following the entirety will become too hard / impossible.

So, I see the solution as filters. Both macro and micro filters. Both group and individual filters.
