Wait. This is amazing. I think there are plenty of potential users. I've already found a bunch of cool stuff near me, and could see using this for any new area I go to. The list of locations could have their thumbnail image as a low hanging fruit improvement. Another consideration is not throwing in the towel after posting once. I've had the same link get 3 upvotes on subreddit A, and 300 on smaller subreddit B. The HN traction goes to show – it's context/timing/audience dependent. Take more shots on goal.
