So, I was just listening to The StackExchange Podcast #20, and they're talking about how to disincentivize people answering simple, easily answered (googled) questions.
Just to be clear, I'm talking about how to keep people from answering bad questions. There already seems to be discussion of how to discourage asking, but people don't always follow those guidelines to discourage askers, possibly because they can still get rep for answering poor questions.
why not, if a question gets closed as duplicate/not useful/anything else, anyone who has answered lose the rep they gained.
I realize no one likes losing rep, but perhaps that's the point.
EDIT: multiple complexities surrounding duplicates have been pointed out. But how about if this was just for things closed as off topic, not constructive, or too localized? I'm also not wedded to this particular disincentive, and was hoping that people might offer alternative ways of using reputation to discourage people from answering questions that don't benefit the site.
I'm trying to discuss something like this question, but about things other than duplicates, which are often easier to recognize and less helpful to keep around (the non-duplicates, that is). This answer also brings up an important point about removing rep on close. Namely that closure is often temporary, and so changes in rep, or notifications admonishing users for answering a question, tied to closure could be useless or annoying.
