On Google Maps I prefer to add videos about doffernet places and events. There are many-many photos, but less videos. I add vdeos, which show the current, ongoing process, events, ordinary or extraordinary situations. For example, when Belgium football team won Brasil, I was just in the centre of Brussels and taak a vidoe of fantastic celibration of Belgian.
At the same time I like to correct the wrong information on Maps, to add new places, which help others to be familliar to not very well-known places.
