I would say the thing that's needed most, and might serve to differentiate from lesser approaches would be to have complete references for each answer given. So the user knows where the raw info came from to begin with, how any conclusions were arrived at, and where to go for further details besides an efficiently distilled answer. Not my downvote btw, corrective upvote actually. It would be good to see more input from a variety of experiences.
