that's an intentional misspelling of "answerable" written as an-sewer-able. I'm attempting to suggest that their cute little slogan (and overall outlook) of "steer clear of the populist tides" is elitist, viewing people little more than refuse.
I picked it up when I had to take stage notes professionally, speeds your writing way up and also prevents hand cramps if you're writing a lot like I was (carrying around a computer wasn't an option, neither was staying in one place or trying to use a tablet).
