If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
A few days back I made a ZeeMap for LessWrong and promised to post it in an Open Thread, so here it is: https://www.zeemaps.com/map?group=1323143
It's basically a way of finding people that share a particular interest living nearby. There is no need to register - just add your marker and keep an eye out for someone living near you.
Maybe this should be linked from the front page?
