If you've not heard about All The Places, you should probably check it out.
While it's probably not licensed for OSM, we do QA with similar data in the UK.
@CjMalone Thanks for mentioning all the places!
I've been tinkering on something similar around Australia. I'll definitely be checking this out more.
@tim so, I don't really at the moment. The only thing I do is to add the website to the OSM object, via the JOSM conflation plugin. It's a bit fiddly, but it works OK most of the time.
In the past I've written code to match and merge bus stops, nothing too interesting.
