Look, I’m just a lurker, so I don’t really have any standing here, but I figured I should explain my downvote:

Every time you promote in here, it’s framed negatively (“we’re more active than you”), rather than encouraging friendly coexistence (“if you want even more movie stuff, come check us out, too!”). Sure, it may just be a difference in phrasing, but to me, it also changes whether your posts actually contribute something to this community or not.
