I created a MapRoulette challenge for myself to verify and merge each point if they already exist. All of the points have phone number data so even if it is a duplicate of a name, it is still going to be merged and thus add additional metadata regardless. I did not want to add the amenity tag before looking at each point to ensure the amenity is not closed anymore. I created a buffer in QGIS before adding the points to rid of most duplicates, but obviously it wasn't large enough for all offsets. The data is opensource from IMLS and the lat./long. coordinates they provide aren't perfect, but better than nothing.
An import is the first step to bridging the gaps, so please don't be too critical, as I am actively working on fixing the state libraries in my MapRoulette Challenge!
