His idea wasn't even "Grindr for teens". It was worse because he wasn't proposing a separate service. His idea was to update those sites to accommodate young people. Yoth wrote: "those services should consider offering toned-down content alongside adult fare."
Even if we're charitable, Yoth's use of the word "alongside" was unfortunate. Less charitable, a serious error. It's unrealistic to expect a service with such a concentrated historical purpose for gay adults, could pivot to a harmonized family-friendly vibe for young and old.
I wonder how he landed such a role at Twitter over other applicants, and what criteria he met, that others did not.
I don’t know much about his proposed solution, I haven’t read his work, but judging by my own teenage use of Grindr (many years ago), a toned down, protected version of something gay teens were already going to use seems like a net gain for their safety and sanity.
I doubt anything like it would ever be legally possible, though. There’s just no amount of moderating that would keep a teen Grindr safe and PG-13. If even one thing slips through - and it would - it’s not hard to picture the media coverage. No sane company is touching this idea with a ten foot pole.
