True. I've found many good and useful things there, but every so often they post something that is clearly dubious or a hoax. That's fine as things go; people make mistakes.

But when caught out they tend (to the extent I've seen) to either say nothing or to just delete the post, rather than make an effort to correct mistakes.

(On a related note, I'm amazed at the level of snark and bile in the some of the comments on Boing-boing; the nasty ones rival or out-do the worst of Youtube.)
