Elsevier is better known for its crappy magazines here in Holland, but yes, it's a big publisher. That's just it, though, recognisable or not, they're publishers. Not universities, not faculty unions, not a board of review, just a publisher, and relying on the publisher's name for quality of the product seems a bit counter-intuitive. Though this case certainly was pretty f'd up. And it came up in the topic because Roflcore brought it in when I tagged Wikipedia unfit for usage for academic and journalistic purposes.
