Set up a "Film of the Week" livestream where users can sign in and watch a movie together
I think Letterboxd should have a "Film of the Week" where every Friday or so at a scheduled time slot, a movie is screened live on the site and users can sign in to watch together in real time, similar to a YouTube livestream. There should also be a live chat so users can comment and discuss the movie while its playing. The livestream can only be accessed by users, thus encouraging people to sign up and build a sense of community. Admin can hold votes on which film to screen for that week so users can spread the word and increase viewership.
