Joe, good point about “Trust but verify.” My concern with Wikipedia is that it cloaks the source in the process, so that it asks too much on the “trust” portion and doesn’t give enough information for the “verify” part.
Take, for example, your Wiki link below. Someone who wasn’t “present at the creation” of the neologism “fisking” would have to trust the institution of Wiki to have the sources to have gotten the definition correct. The individual[s] who submitted the definition is [are] unknown to the seeker, however. What if a fellow by name of, say, Robert Fisk had submitted the definition? The seeker wouldn’t know ? he can’t know where in the editing process the entry is.
