Thanks for promoting wanderer!
Finding trails on the map should be no problem, you can currently mark trails as public so that not logged-in users can see the trail. I have thought of steering wanderer towards a more socially interactive platform. I think a good first step would be to allow comments and implement a rating system.
Thanks for the crowdsourced translation website. I was looking for something like this. I will set it up and add it to the contributing section of the documentation.
