Perhaps we should trust it more because it is fluid and that fluidity is documented (see the history and talk tabs for any given article). Historically, reputable sources depended upon, to a very large degree, the authority of the author. The reader typically had little to no insight into what was generally agreed upon and where there was some debate. How the Wikipedia exposes that may be imperfect, but it is better than nothing.
