Sorry, I deleted my comment because two other people basically said the same thing. I was hoping to get it out before you responded. My bad.

I am not necessarily saying I would rather you post a huge wall of text. Personally, I would just link to a good summary of the material and say, "This has been covered before."

Another way to respond would be to play coy and ask for more details. This, at the very least, encourages more dialogue.

Another solution is to just not respond at all.

None of these are particularly fun, but I like to think you can at least avoid the negative response from the community.
