We often forget that, although it's obvious search engines filter results, the information we see on social sites is also filtered.

Consider users of Reddit. Now most of them would consider themselves very open minded and enlightened, yet their is active discouragement for radical ideas without due consideration as to their merits. It's just easier to downvote and look at Mario cake.

Overall, I think in a way we NEED filters to remove the faff, but be careful to keep a social circle which encourages radical ideas to be bought out into the light of logic and due consideration,
