Would it be possible to make a new tab for each tag that only shows unanswered questions? I've found a connection between the time of the day the question is asked and the number of views. Apparently if it's night in the USA (2-10 ) its most likly my questions will just go under with low views. Even hours later nobody cares about it, because it on page 5 or something like that. I'm from Europe, so if I'm the office in the morning it's most likely most of my SO questions will not be answered.
What I do in such case, is that I delete my old post and ask the same question all over again. That is a bad solution in my opinion. The only other, even worse, solution is, that I try to track the user activity and only ask questions if its high enough.
