alt Hacker NewsI figure from the context of the post they are asking sincere questions to their co-workers where they think their experience and knowledge is appropriate, but otherwise I agree that people should do a little legwork on their own before asking out loud.
The bigger issue I feel is knowing the medium for the question/help you need. If you need their experience and knowledge then talk to them. Email as a medium is already a wrong choice most of the time in these situations. Expecting them to give you the context that helps you grow from their experience in an email is placing a huge burden on them.
