i also use "these for speech or longer quotes in essays" and i use 'these for thoughts (at least i used to) and for single word/two word phrase quotes'. we are right, don't worry. the rest of the world is crap.

my stylistic quirks are mostly to do with in-text citation and reference lists, so i won't bore you with the details. however, i always double space after the end of a sentence (although the intert00bs tends to smoosh it back into one space).
