One of the greatest pleasures of my job is fielding pitches, which range from the bold to the brilliant to the baffling. Recently, GBH staff writer Jonny Garrett sent in an idea that was a mix of all three; as soon as it came into my inbox, I remember thinking—“this is something we have to publish.” That pitch evolved into his recent piece, “TL;DR – Tracing the Origins of Beer Language, from Michael Jackson to Emojis,” which is part of our Mother of Invention series, underwritten by Guinness.
