We do not. We say "give the gift of knowledge."
Small wonder that we're starting to see some hostility from the outside. We're trying to have it both ways. We set expectations ("give the gift of knowledge") and then are surprised when people have the expections we set.
I agree with this. Similarly, we say "From Wikipedia, the free Encyclopedia", not "From Wikipedia, the free Encyclopedia that anyone can edit". Why? Because the community (ok, a very small part of it) deemed that the latter was "ugly". Apparently it's ugly to state the fallibility of Wikipedia in a public way, but it's great to rely on it to avoid responsibility.
Ok, I'm being harsh. But WP really *does* present itself to the layman (ie, the casual websurfer) as being an authority, and it's only when you delve deeper, by reading this mailing list, reading interviews with Jimbo or clicking on the "disclaimer" link, does WP explicitly disclaim authoritativeness. This is, IMHO, a problem. One that would very easily be resolved with some sort of relatively prominent link labelled "Researchers: What you need to know about WP" or whatever.
