Could you all help me brainstorm something?

Do you think there would be any use for a Federated location sharing app? Something that would let you mark an annotate locations in the world to share places of interest with your friends or to publicize things that are happening.

We could make a distributed, location-based search engine that pulls up all of the annotations within some radius.

Yes? No? I’d love to hear if this community thinks it would be valuable.
