On Fluther, I pretty much always read the details, even if they are volumes thick (some of the relationship questions are like that). I’ve found that the details are often slightly, or very different from the OP’s question, or if not different, the details give you something you need to provide a decent, well thought out answer.
If I’m reading the newspaper, I often skim the headlines. I think newspapers, because they are professionally run organizations, as opposed to a site like Fluther, which is mostly laypersons, goes out of its way to make sure the headlines are clear and concise, rather than misleading. I don’t think people on Fluther try to be misleading on purpose, it’s just that sometimes, the questions are not exactly telling the whole story, but the inside details usually do. If not, I will ask the OP for clarification. Sometimes I get clarification, sometimes I get yelled at and told that I’m mean, or that I’m a bully for daring to ask a question about an unclear detail. I’m about as far from being a bully as the sun is from Pluto.
