One mildly negative variety of first-response message occurs when someone asks a question about a song (lyrics, chords, sheet music, history, composer, copyright date, etc., etc.) and the next message says "You shoulda looked it up yourself!"

Almost invariably, someone else supplies the desired info anyway, and there may or may not be further discussion (usually good-natured and brief) about what a wealth of information we have in the DT. But the discussion usually remains on-topic and civil, and includes loads of interesting info related to the original question, plus some other related and unrelated stuff as well.

Speaking for myself, I'm glad when people don't do their own research and post a question to the forum. That way, I get answers to questions I would never have thought to ask myself!
