Where ridicule is needed is cases where someone defends the indefensible, or continues asserting things that are beyond mere ignorance.
The only time I've seen folks go after a typo is when the typo itself happened to be *funny*, or triggered a bunch of puns. Like earlier in this thread when someone typed "viscous" (a word meaning "thick and sticky") when they actually meant "vicious" (cruel). The mental image of a Freeper being called "thick and sticky" was too funny to let pass without some jokes.

Right -- when someone actually *was* behaving in a ridiculous manner, and we were pointing it out.
..... such as claiming that 1720 is a really big number for three days while everybody on the thread keeps pointing to it, and the person who posted it doesn't realize the OBVIOUS typographical error.
