Flockstr g-tag (for geohash) and location map?

The Meetup alternative looks really cool...

I think it'd be way more useful, if I could browse events nearby me in a map.
This is very doable using the standard g-tag in nostr (lat-lng can be converted to geohash)

Let me know if you're interested.
I have a working map, and am glad to help
