Sorry I'm not sure where you're getting 9% from. The link you provide for `currency:XBT` shows 7.35% with a combination of `building=*`. This key is fairly small in terms of sample size though, only having around 17,000 uses.

Checking some more common POI keys though, I believe this is more common of a combination than you think:

`key` - combination % - ~combination total

`amenity` - 10.98% - ~3.34 Million
https://taginfo.openstreetmap.org/keys/amenity#combinations

This also includes parking, so remove ~70,000 for `amenity=parking` + `building=*`.
https://taginfo.openstreetmap.org/tags/amenity=parking#combinations

`shop` - 19.25% - ~1.28 Million
https://taginfo.openstreetmap.org/keys/shop#combinations

Sure these are still a minority in terms of percentages, but to me over 4 million objects mapped this way means its still a fairly common way to map it.

Like these from around the Greater Houston area:

I'm not sure Twitter is a proper source license-wise, but I've left the crypto tags you've added alone.

I wanted to ask why you removed the building? This restaurant is the only thing in the building so theres not a need for it to be a separate node. I've re-added the building and merged the node back in with changeset/168670890

This changeset reverts changeset/168342525 and changeset/168396583

This has been reverted by changeset/168420651

This has been reverted by changeset/168420651

I think something went wrong with this changeset, all of the nodes added here are at (0,0).

I've changed the tagging of this from `natural=peak` to `natural=hill` in changeset/168314108.

Tbh, I don't think this should be tagged as a hill either, but its at least more accurate than a peak. An `ele=12` is barely a hill, but definitely not a mountain peak.

Appreciate you catching that, and thanks for fixing it!

Honestly I have no idea, about a year ago I went through the billiards tagging to clean it up to the standard that the Wiki had said.

I've never heard of Bar Billiards before so at the time I probably just assumed this was a tagging mistake for Bar tables (7ft) as they are generally called in pool leagues, I can change it back if you'd like.

Hi, the POI you added for Big Tyme Billiards is a duplicate of node/11037664808, so I have removed it.

Hey, just wanted to check whats up with these `house=terracedhttps://www.articulate.com/360/` tags, is this some kind of ad or just a copy/paste error?

For example: osm.org/way/1332811976

Hey this is awesome, thank you for taking care of a lot of these streams! I've been meaning to do something about these for awhile and am really happy to see these added.

Looks like a section of this bus route was deleted in this changeset.

Ah alright thanks for confirming, I haven't been down Kuykendahl here recently so I didn't realize they had cleared those trees.

If you ever need anything please let me know!

Hi, thank you for your contribution, just wanted to check why you deleted the natural=wood and natural=scrub areas here when you added the park?

These area types are not mutually exclusive.

Apologies, the bounding box for this is a lot larger than the area of edit since I split the railway here to add a bridge:

osm.org/way/1261371104

Apologies for the changeset bounding box being large, looks like it was because of this crossing I added with the railway: osm.org/node/11668360335

This bounding box was a lot larger than expected, guess I accidentally moved a node on the river when going along there. Apologies for that.

This is to resolve a note, should have waited to close it in iD so it would be in the changeset tags but I closed this before I made the edit and didn't want to reopen it just for that.
