I have done 14k edits over six years. I too like it for being therapeutic. I’d rather do micro-edita on osm than play another level of candy crush. Same kind of reward but you are also helping out creating something larger!
Honestly though, I don’t think osm will ever catch up to the commercial alternatives. Mostly because their harsh stance against automatic edits (and lack of version control). Also the lack of standardization is a problem. It’s very hard to create client applications because the data is structured way different in different regions.
