Letterboxd is kind of a social media, but specifically focused on movies. You can log and rate all the movies you have seen and, I think, share them with others. I am on it and have begun the process of marking movies I have seen and even reviewed about 30 of them.
I have no “letterboxd friends” or whatever they call it. My login name there is also Mahaloth, so I assume that is my avatar/name there.
If anyone is into movies and uses Letterboxd, let use know and perhaps we can connect or “friend” each other on there. Always looking for other movie loves and interested in suggestions.
