If anyone is looking for easy ways to contribute to OSM I highly recommend StreetComplete (which is a gamified quests to answer questions about your local area) and Every Door (which makes it very easy to add/update info about shops or other points of interest (POI) near you.
I did this for a while, but it began to eventually creep me out that the app was asking me to input all kinds of irrelevant details about people's houses, like how many stories the house had and what style/shape of roof it had.
I get that they're trying to slurp up just some of the data a company like google gets from streetview surveillance vans, but I just don't see why any of that data has a legitimate need. I continued using the app a little while longer to fill in other details, like one-way streets in my area, but those sort of queries eventually dried up within the area I usually go for walks in.
Personally, I don't think that the details about houses (like how many stories and shape of roof) are very useful (compared to the other data it asks for like opening hours) so I turned off those quests in the settings. It would be nice if they weren't on be default.
It's a map. Buildings are landmarks. Remember it's not just for routing your car journeys, it's meant to have everything on it. You look at the map, you see a square building. Is it a warehouse, a skyscraper, a radio antenna? Will you be able to see it from a mile away, and if so what will it look like? That's very relevant info. It might seem odd to be collecting data on people's homes, but it can't even guess that it might be somebody's home without asking you such questions. And the info it asks for is public anyway, it's not like you can't find it all out on Street View.
I've been using Vespucci for adding POIs and such, but it looks like Every Door has good sensible defaults that make things easy for a newbie like me. Thank you for mentioning it.
