  • AKA has been supplanting "i.e." in informal writing for some time, but has also been attested in more professional writing, like this clip from the Scientific American blog:

    "There's also the simple fact that one can drill to release a transportable commodity worth roughly $100 per barrel (aka oil) or one can drill to produce a commodity that must be instantaneously transported and consumed at a value of roughly 10 cents per kilowatt-hour (aka geothermal electricity)."

  • Professional writing is not always good writing.

  • Aka is not aka i.e, i.e. i.e isn't aka aka.

    In the sense quoted by billprice, referring to a simple subject or object, aka works fine. But in the broader sense of "i.e." ("that is to say..." referring to a proposition or conclusion) - a "thought" rather than a "thing" - aka is no alternative.

    Better, then, to stick to aka's original meaning, i.e. alias.

  • The CDC definition clearly refers to aka (although the modern sources I can find call Metrosideros perforata by this name).
