Apart from questions that are so horrible that they get closed, do easier questions generally get more activity (upvotes on the question, upvotes on answers, number of answers) than more difficult questions?
I suspect this is the case, but I could be imagining it. And it isn't axiomatic that easier questions would get more activity - in theory some users could decide to ignore questions that are too easy for them.
(For the purposes of this question, "difficult" means that you'd have to have a lot of knowledge or do a fair amount of research in the topic to answer it, rather than the question being "difficult" because it was badly written)
This isn't meant to duplicate The bike shed problem and SO - that's saying "how do we fix the problem?", while I'm asking "Does the problem exist, or am I imagining it?".
