@zverik Still loads of redundant GNS tags on place nodes in Ireland (probably imported by Dermot - mackerski). Until the townlands project got going they were still the major source of places in rural Ireland. Still a lot of dedup & other cleanup needed.
I also did a bit with them for Pakistan, but never could trust the data in a country where the population had increased so much : http://sk53-osm.blogspot.com/2011/03/garmin-overlays-of-gnis-names.html (probably should correct GNIS->GNS
@SK53 yeah, what felt a good idea in 2011, not that much now :)
