I tried it when someone posted about it a couple of weeks ago. It is fun, my son and I go for walks and I include him in the tasks. Unfortunately, we get a lot of road surface questions which are a bit boring.
You can also add "little" objects like benches, recycling containers or trees in your near environment to the map that come with their own sets of questions
If I disable the 3 types of quest I get in my area (road surface, lanes, power pole type) then I get basically no quests, period
I've taken to adding buildings that I'm surprised they didn't already have on OSM and then filling in the quests that auto-populate with that, but its meh
