Very interesting. Part of my says that if it rung and I wasn't the first to answer, I would feel bad. At the same time, I like the idea of being able to reach out and just say "I feel like talking to someone". I would imagine that it is super interesting for people with depression or addiction who could add their support group too.
This is an interesting idea. I'm building https://tend2thrive.com - I could see an interesting collaboration here. Always looking for ways to re-engage your network without it feeling heavy.
I'd love it if you can also fix the problem of timezones. So many of my friends are oceans-apart and we rarely rarely meet and talk as a group anymore. Maybe some kind of asynchronous option?
The idea is to just send a beacon whenever you're free and maybe you'll catch friends in the wildly different timezones from time to time.
I sometimes send beacons on morning commutes. Way too early for normal social calls but will sometimes catch people a few timezones east on a lunch break or something.
