Nikon offers some good advice in the article:

"Nikon and etiquette experts Debrett's offered this advice to those posting pictures on the Web:

* Don't post embarrassing pictures of other people without their permission.

* Ensure that you are happy for the pictures you choose to be on the web for all to see.

* Remember that your boss, family and friends may look at your pictures, so don't post any inappropriate images.

* Don't endlessly post pictures of yourself -- you'll come across as self-obsessed, rather than interesting.

* Think about the impact your photos will have on other people before you share or project them."

LoL

Survey says,it's the Russians of course! They also take the most "intimate" pictures :^)
