I've been using it a lot since State of the Map 2022 for data capture. There are some many low hanging fruit to capture that its really efficient to improve coverage with minimal effort.
It does of course help to know the data model and tag guidance well for the amenities / data you are capturing. But there are opportunities for novice mappers too.
For very novice mappers that don't want/need to add new elements, StreetComplete is probably still the best way to start out, at least if you're on Android.
Do you think Every Door is a good way to do that? Is this [1] wiki the right place to look for the data model/tag guidance you are talking about?
I heavily suggest to switch to https://organicmaps.app/, which is a maintained fork of Maps.me, without user tracking and the whole wallet shenanigans.
You can just enter an amenity:bench poi, but it's useful to include additional information in tags. StreetComplete, for example, has a quest that adds the backrest information.
Osmand lets you add pois, but offers little guidance which tags are appropriate for which kind of poi. Every door seems a bit more helpful in that regard.
