Hi, I'm roptat! I contribute since a few years. I enjoy hiking with a GPS and map features not on OSM yet. I do that usually on vacation, so I contribute sparsely ;).
Also feel free to ask any question :)

Here is a list of tools I know:
- Overpass API: an API to filter data from the map. The most well-known instance is at https://overpass-api.de. You can use https://overpass-turbo.eu/ to use that API directly.
- latest changes: Shows the changes in the last 7 days on a specific region.
Here is a list of maps I know that use OSM data:
Notes and TODO list
- Clean places of worship. A lot of them are from a very imprecise import, see this query. Most of them are correct (at least they seem to be) but a lot are still in random places (in the middle of a road, on a building that's tagged differently, or in the middle of nothing).
- Actually, the import was not about churches or places of worship, but more categories, see USGS_GNIS. This query tries to find imported features with the gnis:feature_id tag that were not modified since the import or shortly after, so mostly nodes that are not accurate (and maybe even gone), but not nodes that were modified after that date, which have probably been replaced manually to a better location.
- Some `leisure=park` from gnis are named “Historic District”, which typically means they are actually historical places, so to be tagged with `heritage=*`. It seems that in a lot of cases, they are listed in nhrp, for instance for New Haven. Follow Key:heritage#United_States. The original document might be found here for instance. If it is published before 1989 w/o a copyright notice, it’s in the public domain, so it's usable in OSM. Make sure to check the copyright notice before using such a document! This list is also interesting.
