I think Wikipedia correctly understands that accurate information is a work in progress and often a fight for one set of memes over another. Time was when the expense of publication provided a barrier to misinformation because with names like "Encyclopedia Americana" (or "Britannica" indicated that only the best and brightest would or could contribute.
Those days are gone.
I use Wikipedia on a daily basis (and sometimes it seems hourly). And I contribute to the effort.
