I agree that we should aim for smart and interesting; my concern is that the perception of what is "smart and interesting" (which is entirely subjective) may simply validate an already-predominant male perspective on interesting content, making people who bring alternate viewpoints feel excluded. For example, content creators on the internet resemble overall demographics, whereby only 9% or so self-identify as black. A population that is not used to considering racial issues, or which does not perceive them as salient, may approach these issues differently than a more racially-sensitive bunch of people and may exclude those with divergent views.
Eventually, each website develops its own ways by which it measures value. There is no objective way to measure interesting and intelligent content, and it will inherently skew towards the ideas and demographics of the majority user group.
