Hello world! This is my first post about sharing on Google Maps theme.
In first i think it’s very important - sharing your own information and photos with another peoples, becouse all over the world need to explore every place what they want, and you need not to visit other countries or etc.
My adding place/photo experience, actually, started not with GM, but with Wikimapia, it’s open-content collaborative mapping project from Russia, as you know, i think 
The main title of Wikimapia it’s “Let’s describe the whole world!” and i try do it.
Only after WM experience i try something in GM and Yandex.Maps, and i still continue to believe what cooperative work peoples from all countries can make all mapping community more strong.
Let’s do it together, in all maps and more interesting and fully.
Thanks!
