I have 75 relatives on Facebook who live around 3000 miles away from me. If I want to share a photo do I send a mass email to all 75 annoying those who aren’t interested, do I BCC everyone so I get repeated responses (and those responses aren’t shared with anyone else who is interested). Or do I post it on my Facebook feed where those who aren’t interested can ignore it (and it will be gone soon) and those who are can have a conversation around it without getting in everyone else’s way?

Edit: ok maybe around 40, not 75. But point still stands, it’s indirect communication rather than remembering about that cousin of an auntie’s grandparent’s nephew’s sister-in-law that I met ten years ago.
