Should a question be up-voted only when it shows research effort and/or is useful and clear? Is a question useful and clear if it's interesting?
Should a question be answered only when the question shows research effort and/or is useful and clear? Does the fact that a user answers a question imply that it is useful and clear?
Similarly, if a third user finds an answer useful and up-votes it, does it not follow that the question too is a useful one?
I ask because I find it decidedly odd to see some questions which have a number of answers (and thereby, a number of answerers), but a dismal number of question up-votes. Do these answerers not find the question interesting or useful and yet deign to provide an answer?
