In (admittedly more formal) writing the rule I was taught was to use any acronym in full at first use with the acronym in brackets, and the acronym alone thereafter. It may seem a bit pedantic at times, but it's a courtesy to readers I think - and as has been said, few if any acronyms are unambiguous.
This is what I do, but I'd rather do away with MFD.
