in reply to Please explain WHY you voted --

Until vroom has the time or inclination to put in a way to tag ++ or -- votes with an identifier for rationale, I simply cannot see myself explaining every downvote.

Sometimes someone else has already explained it, sometimes the problem is well known. Maybe I have a strong bias against the way you solved the problem at hand, but it's a religious thing.

A few times I've made what I thought were excellent suggestions, and I had to endure a debate I did not find constructive.
