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,

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=*

Cool, no worries! As a frequent jogger in the area, I'm looking forward to another access point to the path as well

It also looks like you left the under-construction ways untouched under your redrawn road, perhaps your map renderer of choice doesn't show highway=construction?

Hi, I marked this bridge as under construction a few months ago based on personal survey, has it re-opened? The project wasn't scheduled to complete until December: https://www.culvercity.org/Events-directory/Event-Page-Higuera-Street-Bridge-Replacement-Project

Hello,
I see you reclassified this segment of PCH/I 10 to a motorway. In California, consensus is to tag the beginnings and ends of motorways at locations matching the signs marked "Begin Freeway" and "End Freeway" (osm.wiki/California/Map_features). In this case, I've personally verified that these signs are at the previous transition locations, near 4th St. These segments you've retagged are not up to motorway standards in any case (speed limit 45 mph, no/narrow shoulders). Please consider reverting this change.
Best,
Will

School nodes are often slightly offset because they were imported from GNIS over a decade ago and poorly aligned at that time. Instead of deleting the nodes, which usually represent real schools, is it likely more useful to move them to the correct place. Also, office=educational_institution is more for the administrative offices of school districts, actual schools should be tagged amenity=school.

Hello! You may want to consider the more specific tags tourism=artwork+artwork_type=mural for murals, rather than the less specific tourism=attraction
