The whole idea is a privacy minefield, so it would have to be very carefully designed and implemented, of course making it opt-in. But still, should we even pursue this idea?
So that, for example, even if I met someone just briefly, they can still later see the contact information that I am willing to provide.
Wouldn’t that make it much easier to connect with people who live close to you?
Are there any relevant projects or ideas that already exist?
Telegram messenger has this feature, but I don’t remember any of my friends having it on.
Sadly it just results in spam from pornusers that fake their location
I turned it on once. It was all alt right groups whose motives were to take over the local parks with violence, and some nudist group that appeared to be offline. I turned the feature off and went back to the friendly furry faces of normal telegram. :P
