i was starting to cobble together a project Eddystone (bluetooth le url beacon) dating profile, before google killed the android notifications for eddystone. the inability to communicate digitally with those around us at a bar or at a park is pretty silly. it'd be so neat to start more ad-hoc, non-applicationized communications channels! and a chief use would definitely be, "hi, single and interested!" was talking wi…
When I got my first smartphone, I wondered if there might be a trend of single people setting their Bluetooth device name to the URL of their dating profile. Ideally the profile would have a machine-readable set of fields in (alongside a human-readable equivalent) and an app could calculate if you are compatible with anyone in the vicinity.
The system could still work without an app, though, since the user (when they notice someone they are attracted to nearby) could manually scan for Bluetooth device names using their phone, and browse to each page to check if the profile picture matches the person they noticed.
I know there have been some geo-location based dating services, but I think they have an incentive to make the matching radius as wide as possible, so that you keep looking at their app. On an open system, though, the economics of hosting these profiles should be similar to that of hosting Fediverse accounts, so there shouldn't be the same conflicts of interest.
