Creator here!<p>In anticipation of some questions:
Is this live location? No, only location from someone's public bio. We soon will have notifications for when someone changes their name to have "(in SF)" when refreshing profiles and checking latest public Tweet locations if provided. We kept it basic for V1.<p>Is there opt-out? Yes. The simplest opt out is to not include a location on your Twitter bio. Shoot an email or hit the chat button, this info is already public on peoples profiles if they type their location.<p>Let me know thoughts + Check out Antarctica on the map!
