Hi. Please do not use the name= tag to describe features. Instead, you can use tags, such as sport=tennis in this case.

Hi, welcome to OpenStreetMap. It looks like you changed this building=industrial to landuse=commercial. The landuse tagging indicates that this is not a building, which I don't think you intended. To indicate a building is used for commercial purposes, use building=commercial (or building=retail if it's a shop). Also, what was your source for this edit?

Hi, it looks like this feature already exists, added by you one month ago: way/421682350. Also if this not currently used as a bank, it should not be tagged as amenity=bank. If you don't mind, I'd like to know your source for these edits.

Hi, welcome to OpenStreetMap! It looks like you changed this bike path (highway=cycleway) to a freeway (highway=motorway). Did you mean to do that, or do you want to make a different change?

Hi, welcome to OpenStreetMap. It looks like you changed the names and addresses of a number of buildings to all be the same, and in fact deleted one building in a subsequent changeset. Did you mean to name this district instead? Also, what was your motivation in changing Olvera Street from a pedestrian street to a path?

Done as discussed here in changeset/121344263

That's fair enough, I agree that the node's name="Lake Hollywood Sign Vista" was artificially constructed. I plan to revert your deletion, but remove the name tag, and retain the description="View of Hollywood Sign and Lake Hollywood".

Hi, viewpoints need not be officially signed to be mapped in OpenStreetMap, see: tourism=viewpoint. They simply reflect locations with good views (which are legally accessible by the public, as this location appears to be). Can you explain your rationale for deleting this node?

Hi, what is your source for this edit? This appears to be a normal house, and the organization's website lists an address in San Rafael (https://www.idausa.org/about/contacts/)

Hi, are you personally familiar with this area? From street level imagery, it looks like the Bel-Air restaurant is on the other side of the street, and the website you provided gives a different address than what you entered.

Also, more generally, it's better practice to enter the names and address tags of objects in mixed case, so "The Bel-Air" not "THE BEL-AIR" or "Los Angeles" not "los angeles". You also don't need to duplicate tags between a building and a node, just one or the other is enough

Hello, and welcome to OpenStreetMap. Thank you for adding your business. However, the description key is not for advertising messages, and such messages will continue to be removed. See description=*.
Best,
Will

I'm not sure if you were asking sarcastically, but yes, on the ground surveys are the most reliable way to add businesses to the map in a way compatible with the OSM ODbL license. Using other map websites, like yelp, yahoo, google, etc. is not allowed, typically because their terms of service forbid it, so keeping the data on OSM would leave it open to legal consequences. New mappers adding data from such disallowed sources has been a long-standing problem in OSM, hence why people in the community are quick to jump on it.

I've gone ahead and updated the tagging of these four places here: changeset/120647515, after another user took a broader look at some of your changes elsewhere. It seems that in general your tagging choices are not in line with the community's consensus, and that I'm not the only person to take some issue with your edits. I hope you can learn more about OSM's tagging guidelines and appropriate data-sources, and continue helping to build the map to make it more useful to everyone.

These tags are pretty well accepted by the community: there are over 5,000,000 worldwide uses of the 'shop' key in the database, and over 75,000 uses of shop=furniture specifically, for example. You can look up these kind of stats here: https://taginfo.openstreetmap.org/tags/shop=furniture. Many data consumers, including map renderers like Carto, the default openstreetmap.org map, use these tags. If these were tagged as shops, they'd render with purple icons depicting the type of shop, for example. On the 'Projects' tab on taginfo, you can actually see a list of projects which use a particular tag; there are dozens that use shop=furniture. These tags are especially useful when the names of a place don't contain info about what kind of place they are (like "MADERA"), and for easy searches (as in, say I want to find all furniture stores within 5 miles of me: I can just search for all places containing a shop=furniture tag). You're absolutely right that we need to make the data accessible for all potential users, and I think including more specific data is only a benefit for the variety of use-cases people have for OSM data. I'm interested in this map your sister uses, can you point me to the site and/or its documentation?

Hello, welcome to OSM! What is your source for creating this hotel? This looks like a normal house, and I can't find any info on the internet referencing it

I believe this restaurant has already been mapped: node/3960933189

Hi, welcome to OpenStreetMap. Names should be reserved for formal names, not descriptions of an object. Where did you get the name for this "croissant" house?

That is what you've named this building, but what does it correspond to on the real world? As in, what is going on at 5745 Hill Oak Dr, which looks from the outside like a normal house? From the website you posted, Guilded Gamers appears to be an NFT, but I don't see anything about a physical location. I see you've since deleted the car dealership node, but the name on the house remains.

Hi, welcome to OpenStreetMap! This map is a crowdsourced map of the world, and as such we only map real locations. You've tagged this house as a car dealership, does it exist in the real world?

Hi, welcome to OSM, and thanks for adding these businesses to the map! In addition to adding the names, it's helpful to both map users and data consumers to also add tags describing what sorts of shops they are. For example, these businesses look like they might be shop=furniture, shop=interior_decoration, or shop=kitchen. You can see a whole list of potential shop tags here: shop=*
