Show HN: A simple 'lost & found' side project

I started foundcamera.com as a basic weekend project a little while back.

I hoped to help a few people out and potentially facilitate some great success stories.

I thought it improved upon what's out there already as it's super simple (no signup) and it puts the geographic element at the centre of helping people to find & return treasured photographs to their owners.

It's recently picked up in popularity and I'm adding more lost and found items and seeing several hundred visitors each day. No successes as of yet.

Any suggestions for getting more people to play detective and help return items? I want to get some green pins on the map!

Are there any non-intrusive ways I could monetize it? Not to make a profit but at least to break even.

How could I improve it for v1.1?

Thanks
