OTN 

"of the now" - usually used in various photo micro-blogging services, but use has not been limited to such.

Sometimes "of the nau/nao."

Used often to tag so people know that the photo is more a "snapshot of life," and there might not be anything more then your current reality viewing experience. It can also be used to humorously trivialize commonly occurring bizarre experiences (see second example).

Example 1 (general use):
Subject: "Kitty OTN"
Data: a picture of the cat sitting in front of you.

Example 2 (humorous use):
Subject: "Crazy lady OTN"
Data: picture of some woman on the bus you are in raving while being pulled out the door by police
