The reason that I love to share on Google Maps is being the first one to discover new or unpopular things/places to keep my adventure motives.
Taipei City is kind of crowded to most foreigners but not me. Small area constructions and narrow roads/lanes make me comfortable to ride my Brompton here. I usually spend time to travel between my office and home by the bicycle. Finding out the special/interesting things is much fun to an ordinary day.
Sharing things that no one did before and increasing my points/scores of Google Maps keeps me go further and helps others if they do think so.
