Just thoughts, too long for comments.
You are right, this is absolutely a pressing issue for SQA - and, we only get a part of it - there is a substantially larger number of "cannot find element" like questions on SO (I've been following
selenium tag there for quite a while).
On one hand, having these questions help with "Questions per day" stat which is crucial for SQA being in beta. On the other, this kind of questions are too specific and narrow - helping this particular person with his "locator" problem has a very low probability of being helpful to anyone else.
Plus, for some reason, this kind of questions are usually low-quality - they usually have markup issues, not enough data to help - e.g. missing link to the actual page they are working with or absence of the HTML representation of the element an OP is trying to locate.
And, commonly these questions are getting abandoned by their OPs, leaving an unaccepted question as a result which does not help SQA with the "Answered" stat.
But, yes, I am up for the changes and improvements in this area.
