@dewey looks interesting! I'm a Swarm user since many years and always wanted a selfhosted, #OSM based alternative. It's life logging for me. I like the return of badges. Wondering how an Foursquare import would match the OSM POIs...
@pr3d I was actually surprised how well the matching worked. I've only had to manually review ~15 uncertain matches out of 2000 or so. The name + coordinates work really well with some naive implementation of text similarity. I can't say if 100% are correctly matched, but so far it seems like it.
