GAAP is not an uncommon acronym in tech circles. For example, listen in to any earnings call or read any of the big tech companies' quarterly earnings press releases and you'll find references to GAAP all over the place. Quarterly earnings are a pretty common subject of discussion when they occur, so I wouldn't be surprised if a lot of programmers are familiar with the term.
I have to agree - I see it mentioned a lot throughout articles, tweets etc when discussing funding or earnings. I've never felt it was a particularly 'accountants only' term.
