The new OSM editor is a pleasure to use and I've been inspired to fix up my neighborhood a bit. It was cool to see these historic homes (designated Fort Collins landmarks, in fact) pop up in MapBox just minutes after I submitted them.
Google Maps, on the other hand, has no historic homes and a rather outdated and (sadly) never to be realized development proposal in the neighborhood. Fixing Google's map for free is not high on my list of priorities.
Next, I'd like to finally get some Pleiades-related data into the OpenHistoricalMap sandbox.
