I remember posting an answer to a CGI question with some grody, idiomatic solution, and getting scolded/downvoted by a high-rep dev (who montiored the subject tags) who responded with... a solution that didin't work! When the original asker responded, they directed them to file a bug.
That contempt and disregard for the actual day-to-day tediousness of writing commercial code is an attitude I can do without.
