One of the problems with Wikipedia is that it's so easily editable; it's for that reason that the archair experts who tend to dominate the comments sections in news media - routinely citing Wikipedia to buttress their arguments - can be so easily discounted. Anybody who relies upon Wikipedia as a source carries little credibility. And as it happens, they've got another problem on their hands:
In a statement released Wednesday night, the Foundation announced that Sarah Stierch, Wikimedia's program evaluation community coordinator, would no longer work for Wikimedia.
Why? It appears that she was taking cash payments in exchange for modifying entries. Although it's been rumored for years that such practices were occurring, this was an especially egregious - and demonstrable - example. And while certainly Wikipedia contains a great deal of absolutely correct information, it also contains a fair amount of disinformation.
Take nothing at face value.
