I apologize to those who in the audience who do not care for social networking, but as a part of the generation I am in it would be imprudent to not discuss the differences at some point.
Social Networking, as some of you may have learned through the events of the Arab Spring, is becoming quite worldwide. Chile is no exception. The use of Facebook (especially), Twitter, and others have infected the entire nation.
If I were to say one thing about Facebook use in Latin America, I would say that it is abused. EVERYONE has a Facebook account, and EVERYONE spends way too much time on it. For example, my host mother (70, who I adore) spends a majority of her free time on Facebook (3-4 hours actively/day). She will post a status, and then choose to "like it". For those who understand, that just isn't done.
In my family alone, my host brothers (39 and 27), my host sisters (45 and 43), host nephews (16, 13, and 12) and my host grandmother (90 something). The only one to have held off is my host-father. In that respect, I think his stubbornness is acceptable. The problem of Facebook is not just a problem in my family, but many others. Some students (one in particular I don't care for) have gotten in trouble from their families for translating a post/comment to Spanish from English ripping into their host family.
Twitter isn't nearly at the level that Facebook is in Chile, yet still has its presence. Twitter has played a serious role in the student movement currently sweeping the nation. Just as in the U.S. and other countries currently with manifestations, Twitter has been a source of organizations and support for such movements.
Being that much of the population lives in Santiago and Valparaíso, this is where the majority of the "tweeting" is centralized. My city of 300,000 hasn't quite got the "Tweeter-Fever" yet, but I am sure it is on its way.
Social Networking, no matter your opinion on the issue, is ubiquitous and omnipresent. I find this to be a shame, but the majority of the youth (and seemingly increasing amount of the older generations) would not agree with me.
