People are rarely criticized for consuming content - watching TV, going to movies and concerts, reading books and magazines.
But producing content - editing Wikipedia articles, blogging, Quora-ing, seems to get under people's skin.
We can probably all agree that producing content is a better way to spend time - it keeps you sharp, develops new relationships, leaves a work of lasting value that may pass the test of time.
But somehow it bugs people. You get eye-rolling, with a, "who has time for that?"
Perhaps because the shift from a consumer to a producer culture is a new phenomenon - and people don't like things that are new, especially when they are stuck in the old.
Or perhaps it makes them feel guilty - they spent last night watching Kardashians reruns. You spent an hour writing a piece that was read by 100,000 people and was reprinted in Forbes and translated into Arabic. Yet you are the one defending why you are wasting time.
The shortcut I usually use is just to ask people if they watch TV. If they say yes, I just say that I Quora instead and get way more out of it.
