When I read "privacy nightmare", I think of a system collecting or revealing information without the user's knowledge. As I understand BeReal, the user understands exactly what information they're sharing, and with whom. That said, I'm puzzled by why anyone would want to participate on either side.
Here are some things I might be doing in any random time window in which such an app might prompt me to share a selfie:
- Eating food, usually not interesting food foodie friends would like to see
- Walking, usually somewhere pretty boring
- Sitting on the toilet
- Writing code at my computer (often code someone is paying me to write and wouldn't like included in a social media post)
- Picking dandelions to feed to the goslings at the park
I don't want to share any of those activities with my friends. If we're catching up on life in person, I'm not going to talk about any of that. If any of my friends do want to see those moments, I'd find it weird and voyeuristic.
The interesting moment I do want to share, and people might actually want to see is the close encounter with the wild gosling taking the dandelion leaf from me.
