Take these questions:
which is better, windmill or selenium? (selenium)
which is better, linux or windows? (unix and linux)
All of them have accrued large amounts of off-topic votes (and virtually no other votes). But aren't these ON-topic questions for the sites? They are far too broad and very subjective when asked that way, but are by no means 'off-topic'. If an avid selenium, linux, or drupal user sees one of these questions listed as off-topic, they will probably leave the site
I normally vote these as 'not a good example' because they are on-topic, but should not be asked on the site in this form. How should I vote?
