Well, I am not as harsh as KM but I am willing to vote a post down occasionally. I may have even voted down the "chomp" one, simply because at the top of every page in perlmonks there is a search box. Enter "chomp" into this and you get a nicely formatted man page all about chomp. Heck, I bet I could even make some links to it: chomp and chop. I save most of my votes for positive votes. If I use those up and still have some left over, then I vote down empty posts. Then deragotory/off-topic/etc. posts. I also think that someone could very easily vote a post like that down and give a nice polite reply.

Voting down is not always meant as a dig at the post or the poster, per se, but as a way of helping the "better" questions filter to the top.
