In episode 42 of the Stack Exchange podcast Joel Spolsky mentioned something along the lines that some sites (for example, Travel Answers) suffer a little from questions that don't always get useful answers - even when someone has good intentions.
So, for example, someone asks a question about getting a visa. It's tough and a rare visa, but nobody who has been online that day sees it AND knows the answer, so it gets no response.
However, Joe from Kansas sees it, remembers his cousin got a visa just like that, he thinks. He writes an answer that his cousin got a visa for that country, despite it being not quite the same, he thinks it'll be useful.
It's not necessarily useful, but now the question is 'answered', and vanishes into the ether. Obviously, the OP isn't going to accept the answer, as it's not really right.
We do have a few of these on Travel Answers, as well as many, many GOOD answers, to be clear - but what can be done about it?
- Vote them down? This will make it still 'unanswered with no answers > 0' if we're lucky
- Delete the answer? Odds are someone else coming along might see it and find it useful in a very similar situation
- Change to a comment? Some of these are quite detailed (especially visa criteria and laws) that most of us wouldn't know to change it or not.
Any suggestions or solutions that other sites have found?
