Both of those questions have a single problem: they are crappy enough to merit closure.
The first question is just 2 sentences and an image, there's nothing to start answering apart the only symptom.
The second don't even has log files. It would be improved if OP provide better information that isn't just a screenshot (screenshots aren't even searchable), but sadly the problem is already fixed and nobody knows why or how.
What I'm getting at is that those questions aren't up to our quality standards. You are thinking that our answered rate is so low because there aren't people answering, when is totally the opposite, the people asking questions just don't provide enough information to be helped which just promote the bad practice of guessing the solution. We are about clear questions with clear answers.
BTW: stop thinking that community wiki is for something other than for people that belivesbelieves that their post are part of the community. CWfication isn't for poor asked/answered questions.
