Each constraint, and what we did about it.
A film is only half-watched until you’ve told someone — Letterboxd turns viewing into belonging.
Outcome, with the source of every figure.
By making film-watching a shared, lasting record, Letterboxd turned a tracker into a community — the kind of product members open after every single movie.
