Hi!
In this changeset I spotted you added garbage dumpsters.
The convention of OSM regarding amenities (unlike trees) is not to map every object, but to map one place that serves as certain amenity as one.
E.g. on Parpetzi near Tumanyan, there should be only one point of mixed garbage collection.
However, currently there are 3 separate points of separate waste collection... because of pitfalls of import. (They should be merged eventually form 3-2 points of red/blue/yellow/glass containers into 1)
