I'm not sure if there's interest in this, but I'll throw it out there and see if anything sticks. I'm curious to see how far the TTOL network reaches. Maybe I have TTOL'ers in my city, Austin, and I don't even know it! On the site, you can drill into each member profile and typically see a member's home city, etc. But it would be cool to see it on a map (very generally speaking - no specific home addresses, of course.). If you want to participate in this experiment, fill out this brief form. I'll load them into a BatchGeo map and post soon.
