American english does it all wrong. When using quotes, don't let the punctuation invade the quotation. Like this:

He said "hello". Or, their names were "Jean-Luc Picard", "William Riker", and "Data".

See how the periods and commas are outside the quotation marks? That's because it makes goddamn logical sense to do that. You shouldn't write punctuation inside a quotation unless it belongs there. Think about it for a second.

This is okay: he asked me "why is The Next Generation the best Star Trek series?" That makes sense, the question mark being in there, because it's a part of the quotation and also completes the sentence as a whole. Nevermind the assholes who try to tell you it's always best to put the end-punctuation inside the quotes, because sometimes it doesn't make logical syntactic sense to do it.

This was a strange rant, but writers should appreciate it. British writers already follow this rule, because they grew up in a better country, and probably write a lot more than Americans.
