I actually have seen folks complain about missing semicolons. Luckily, they did not take the stance heavily and getting them to discuss it immediately led them to agree it didn't matter.

I go so far as to say any coding in stuff like google docs can miss items like semicolons without a bat of an eye from me. Sure, they are typing. But if it is not their normal coding environment, the aesthetics and finer points of the language are... superfluous at best for the points I generally care about in that kind of correspondence.
