Good questions! And thanks for sharing your experience here. Much appreciated.
Here's how it works:
-
Offline status: Right now, friends see your last set level indefinitely. No timeout yet, but you're right that an "offline/last seen X hours ago" indicator would be useful - adding that to the list.
-
Nickname privacy: Yeah, the username is in the share link by design. The nickname is more for personalization (some people prefer going by a different name with friends) rather than privacy. Per-friend nicknames is an interesting idea though.
3.Keeping it updated: Fair concern. I'm betting people who actually need this will keep it current. But it is homework to do, for me as well. I'm thinking about the notification option, though I don't want to be too intrusive in a world of constant popup notifications. The key is finding the right balance.
Thanks for the detailed breakdown of the flow, super helpful for people deciding whether to try it. I didn't post it myself as I thought it would spoil the experience of discovering something new and fun.
