Just to clarify, I am not a power user. If anything, I'm less active than the average Quora user. My problem isn't really with the content of Quora, that's just a manifestation of a larger change that is happening — a shift from a Q&A site to a social network.
"<power user> has gripes" => "<site> is dead".
you're either following the wrong topics, people, or just don't have a sense of humor (that bread question was funny as fuck)
there's still tons of high quality content on quora
