I fully agree with the first paragraph. This issue is compounded by the flood of naive questions: patronizing users will thus spend less time reading decently written questions/answers/comments, and their reading comprehension will suffer from that. End result: even if you posted something that was actually helpful, you can easily get downvoted.
