I see a few questions posting a link to a website and asking, "Cool? How do you do that?" with nothing else. I imagine the questioner may not have a clue about relevant buzzwords or "hidden" (not obvious in source) technologies at play.
So, I think it's a fair question to gain knowledge, but is it really appropriate for Stack Overflow? Often the protocol is to post a question and relevant code or answer "What have you tried?" So, if you don't have a clue, should you not post at all? Or is there a better place in the Stack Exchange network or in the larger web?
