I'm also a 15 years old teenager living in Argentina, but here things are somewhat different.<p>First, no one has a "real" smartphone, most are cheap Nokia phones with some applications for Facebook: People who have money usually buy BlackBerries, I have a Samsung Galaxy Ace (Being an Android fan) that I bought in Spain: but truth is smartphones are really expensive.<p>Facebook... everything is about Facebook here: Teenagers don't use any other IM service besides Facebook Messenger, they even use it in their phones.
I find it extremely painful to communicate because I need to keep a Facebook window tab opened if I want to chat with someone (Well, I use Pidgin now).<p>I don't even go into Facebook, the Facebook feed looks like browsing /r/funny New in Reddit, people don't post original content: Just memes copied from the internet and cristian stuff.<p>People tend to have a lot of friends in Facebook: I think I don't have more than 50 friends: Those who I really would like to talk with me and have access to my pictures.<p>What people <i></i>really<i></i> use here is ask.fm , I'm not sure if people in other countries use it: but the basic idea is that you create an account and people (Logged, or as Anonymous) post you questions and you answer: Then it gets posted in your Facebook.<p>I don't understand why would anyone want to use that service: The questions are dumb and nosense. Other questions are personal, and some people still answer that.
Nowadays most of my Facebook feed is 75% ask.fm links, it's really annoying.<p>Other services? Some people use Twitter, but not really; mostly teenagers following One Direction and Justin Bieber.<p>Blogging? Nah, no one reads blogs: they don't like reading anything larger than a couple lines of text (I think this: <a href="http://www.theatlantic.com/magazine/archive/1945/07/as-we-may-think/303881/" rel="nofollow">http://www.theatlantic.com/magazine/archive/1945/07/as-we-ma...</a> can be relevant).<p>Youtube... they like dumb vlogs and some people like gameplays, I find this kind of videos very annoying and dumb.<p>Oh, not even mention Mail: most of people can't remember their passwords, for me, Mail is vital.
Tumblr? No one knows what that is.
Ah, no one uses Instagram either, and I'm glad...<p>So resuming: Teenagers only use the internet for Facebook, and, sometimes, reading the Wikipedia (When they have to do something for school) and that's <i></i>really<i></i> bad: They have a wonderful tool that they don't want to use, although the language (Most of teenagers don't have a good level of English, or at least they refuse to read English) can be an impediment.<p>For me the internet is amazing: you can learn whatever you want, for free, thanks to tools like Khan Academy, Coursera and Udacity: But people refuse to, and the language is not the only issue. I think we should focus our knowledge into motivating the Teenagers to get interested into this, instead of developing more applications like Poke or a Facetime killer.
