A broadcast may be worthwhile when it carries measurable value and: produces unsigned side effects [0]; produces manageable signed side effects [1].
I’m 24, deleted Facebook at 18, WhatsApp last year, and I too am all calls (and emails for longform or bit sharing). I still observe HN, Twitter [2], domain-specific newsletters for value, and occasionally share when there’s value to be added.
While I might have to manage debris, I see value.
