What prevents people from asking questions on Fluther?
Half of the questions I end up asking are generated in private conversations with other users.
Often I find something they ask me to be insightful or interesting. I will suggest that they ask the collective, as long as we are both on Fluther and people seem to appreciate an interesting question.
Most often, they request that I post it, or no action is taken.
What is preventing people from pushing out these things they are curious about?
