Maybe one string field on profiles and perhaps a date for expiration?
Sure
We want Buddy Lists! 🫂🤣🏃

What are buddy lists?

Well, whether someone is online/active can be deduced by their actions cause it’s all public. Perhaps clients could show a green solid circle when someone is on.
This could be simple enough, just query relay for any event by the author and use that as the last active time
Oh, nice…so maybe status could be color coded based on how recently the user was active.
What about the ability for a user to set a custom status? That would probably need a NIP, right?
A way to know which of our fellow Nostriches are online, on an opt-in basis of course.
