I just saw something on that bastion of excellent writing and grammar, Facebook, where someone's Twitter post is being shared around so it can be jeered at for referring to the Holocaust as the "Hall of Cost" - an unusual (perhaps Freudian) slip, given the appalling cost to humanity.
The clincher was one of the jeerers in the comments, who wrote " Well, he may have the actually spelling wrong, and the actual name of the Halocoast...." Presumably some saintly beach resort, somewhere.
Grins. I love irony.
There's another message board which I frequent, which has "coined" an Internet "Law" of its own (called Gaudere's Law, after a poster thereon, with that online name, who has seemed to be a frequent victim of the phenomenon concerned). Which is, that anyone who makes a post correcting another poster's spelling or grammar, is extremely likely -- if not outright guaranteed -- to have an error of some kind in that very post of theirs. Admittedly, this is usually a matter of typos, rather than of being wrong / mistaken oneself. However, it tends to make one wary of perpetrating such correcting-type posts !
With "the highly ignorant correcting the highly ignorant", though -- absolutely: you've got to laugh.
