Wikipedia is pretty cool. I've used it for a lot of reports. Of course, I checked it with other places and it always checked out. Sure, some articles are messed with. But they get changed back and, if necessary, the article will be locked to make sure that it's safe.
If you don't like it, change it. If it gets changed back, tell the administrators.
Hmmm is it wikpedia or fr lol :-)
