Note that facebook could have handled this by letting users filter, exactly how G+ does it where you put your friends together in circles then you say, "I want this circle, now I want this circle"... FB is controlling that filter because they want to monetize it. They could have allowed you to control the filter, by allowing you to put people into groups then you could, say, show all posts by users in certain groups. But then facebook loses control, or as they might say, "we know best wink wink". Facebook wants to be the gatekeeper for what you receive, and they stand to make a tidy sum off of that. They could have allowed users to filter based on group.. G+ does this. But Google makes their money differently. Facebook has chosen the monetization path. Shareholders want to see revenue. Facebook will say, "Hey, we need to fight spam." Fine, but in G+, I fight spam by filtering on circles. Why can't facebook do that? Less money.
