unclear if the Rensselaer city node www.openstreetmap.org/node/158800698/history/10 and or the other city nodes in this changeset https://changeset/166503648 as noted by the author's changeset comment should be changed back to what it was or not, but if so those changes could be made if its appropriate.

has this building really been demolished? way/266195257 I dont think it has but anyway if it has then this building is not tagged correctly, if it hasnt then suggest removing all the tags that say it has.

looks like this entire shopping plaza has duplicate poi information on most points and buildings that could be merged into 1 entity for each poi to reduce the duplicate information. However, the structure of the shopping plaza looks like its representing each store as a building, but could instead have one large building to represent the structure and individual pois as points to represent each store instead. either way something to clean up the duplicate info could be done here

should this stream be a drain instead?

suggest merging poi to area to remove duplicate information for this library

name tag for trees should not be the species name, suggest using the correct species tag for trees instead: natural=tree

technically as far as I can tell this train station is a station in name only, no passenger service comes out of this station, its currently used for the Revolution Rail bike trail. If this is the case, tags on the station building itself and the stop location could be updated to reflect its current non-rail station use perhaps with life cycle tags.

the canal section in this area should probably be tagged as derelict since its not in use and has no water here

canal in this section still has water in it, suggest adding water to the sections of the canal that are still open and have water in them in this area

user Milo Miller has put what looks like a lot of spam on the map, in particular in this area. I have tried to cleaned up what I can verify but others please take a look at the users changesets most are suspect and there is more to address...
