if you like taking pictures of yourself. I see a lot of tourists come here - mainly Asian - using them. They sit at the tables in restaurants and take pictures of themselves eating or giving the inevitable peace sign.
Gee, what's happened to society? I don't know about you guys, but where I come from people used to ask other people if they may be so kind to take a picture of you, and most of the time they gladly helped you out. Guess that was before the time people used to make senseless pictures of themselves to post them to their virtual friends in passive-social networks...
If you take shaky pictures now with just using your hands, they will be really shaky when you put your phone on a 3.5 pole
Clouds need (useless / senseless) stuff to become filled... ..anyway I find selfies kinda funny, it just assumes the photographer itself to be on the same pic...a selfie stick would be too much for me, though, lol...
