You guys worry too much :)

Personally, I'd be happy to meet someone who has read LW even if they aren't around the community anymore, so I don't get what the concern is. The map may have "LessWrong" in the title, but it's really about meeting interesting people.

Particularly as you are a relatively recent joiner, how much confidence should we have that you will be around to manage the location map in future?

I'm actually not new - this is just a new account. I don't see myself leaving LessWrong anytime soon. Regardless, if I disappear I don't see why someone else can't take over. I just changed the security settings to allow for anyone to export the data. Gram_Stone suggested circulating the map around survey time. I think that would be a good, predictable time to update people on the state of the map, including notifying them of a possible change of hands.
