Its funny that in typing up the title of this question the first suggested 'similar question is 'Downvotes. Why?' which was subsequently closed. Maybe I just picked a bad day but the 2 questions I went to read about because I was interested in both had a downvote (without any explanation) which is a little lame but one had 1 vote to close and the other had 2 votes to close neither with explanations why, thats more than a little lame.
I know we, as a community, don't want bad questions to linger but excessive policing not only turns people off from asking questions it prevents questions that people may not understand or may not like from being asked and then we may as well start burning books.
I don't really know what can be done about it but...
