To get dem HubPages accolades, yo. Gotta ask a lot of questions, and answer questions, for those virtual trophies. They're important!
Also, narcissism. This is the generation of "Me!" where your answer to their question, even if well thought out, doesn't matter. What matters is that you agree with them. Most questions asked here at HubPages seem to be rhetorical, rather than genuine. Things like "Why is Donald Trump such an idiot?" or "Why is Hillary so corrupt?" are perfect examples.
The sheer volume of questions, and the "quality" of those questions, are asked by what seems to be only a few people. It's annoying, to say the least.
