OpenStreetMap
On the https://wiki.openstreetmap.org/wiki/Tag:highway=steps wiki page, there is a section on Possible tagging mistakes. It calls out the incorrect use of https://wiki.openstreetmap.org/wiki/Key:steps. steps is an alternative tag for step_count. It is not meant to be used with yes/no. So I have been using this overpass turbo query to identify all nodes with incorrect steps usage.
[out:json][timeout:25];
// gather results
way["steps"~"[^0-9]"];
// print results
out geom;
This is a pretty easy task for me to get back into OSM mapping. It also helps me keep up my status with OsmAnd’s Free map updates for mappers

Good work, Alfred. Are there sufficient results to merit a MapRoulette task?
Cheers,
Chris

Hi Chris. I wasn’t aware of MapRoulette. Checking it out now.

Hi, Alfred.
I should have added a link. MapRoulette has huge potential. As a contributor, ie, someone who works through the tasks/ challenges, I’d ask anyone creating a task, to make it a manageable size. People working on the tasks, get easily put off by neverending tasks.
For example, if a task was created to correct the use of ‘steps’, have a look at how many results the query produces. If it’s over 150, then maybe reduce the geographical area on which the query is run, so that number reduces. So intead of a task for a whole country, perhaps reduce it to state/ county > city.
I’m working on a UK task at the moment, to correct overlapping buildings. The task has 500 results to check and correct. This is still a little big for my liking, and I think more people would contribute if the tasks were smaller. I was having an email conversation with the task creator (Hi, Marjan @TomTom), and I asked her not to tell me the total number of overlapping buildings in the UK. Little and often is the best approach.
If you are interested in creating a MapRoulette task, I think it’s probably best to clone an existing one, and just tweak it.
I hope you find MapRoulette inspiring; we can make the world map better, one edit at a time.
Cheers,
Chris
