I don’t care about Karma, but to see a 0 after spending an hour on something means that it will not get seen (when I thought people would enjoy it). So in a way it invalidates my effort, and causes me to reevaluate what people would like to see (and, it seems my content may not be it).
ABRP (ABetterRoutePlanner, the best routing software for EVs) uses OSM. FYI for any EV owners.
I update OSM all the time. Agreed it’s super therapeutic!
