Ashley Fetters in The Atlantic:
On Aug. 18, 2011, a thread titled “I design tampons. AMA!” appeared on the news-conversation website Reddit. Hosted by a user named “karnim” who identified himself only as a college-aged male research-and-development intern at one of the “big three” tampon brands (Tampax, Kotex, and Playtex), the thread began with a polite invitation to “ask me anything” (AMA) and a disclaimer. “Much of my work is confidential, so I can't give details about my projects,” karnim wrote, but he could answer “overall” questions about tampons.
In the grander canon of AMA threads—online Q&A sessions hosted by Reddit users with compelling life stories or careers—karnim’s wasn’t the most glamorous or flashy. President Obama, for example, participated in an AMA in 2012. But karnim soon found himself avalanched with reader questions about tampon technology, ranging from the curious (“Why don't they just stop making the cardboard ones?”) to the wisecracking (“Can you make medicated tampons to make women stop actin’ fool when they get their menses?”) to the imploring (“Can you please make tampons with a black or flesh-coloured string? Please?” “How about one that you can leave in for 10 hours and not worry about it?”).
