I would not want read questions which could be solved by searching their titles in google before that they are published in perlmonks.
I do not want to read answers which make the OP feel ignorant or stupid. Personally I think a much better strategy is to simply not answer a question that you deem lazy, and if a question is left entirely unanswered the OP will surely get the message. Answering with sharp comments also wastes the time of other Monks (unless those comments are witty or humourous).
And easily answered questions can provide a good practice space for those Monks who are just beginning to (try) answer questions. As BrowserUK points out, tolerance of the unwary beginner is what sets this place apart.
