I saw a VIVA ad on the Los Tiempos newspaper on Sunday and and another one of TIGO at a nearby store today, it 's funny that they promote mobile web access to Facebook as if it was a plus of their service. This is probably due to the fact that many young people in Bolivia are Facebook addicts. No joke, I have Facebook contacts in their teens which have 500+ contact easily. For a country where about only 75% of the population has access to electricity and where from 10 million tops about 1 million people have access to internet, believe me 500+ is a lot.
In Bolivia Facebook use has grown very quickly, nobody uses MySpace or other social sites, basically everyone who has a social account is using Facebook. Twitter use is reduced, the other day I had a friend who was at what they called a "Twitter Party" in Cochabamba (he told me there are about 30 users of Twitter he knows in Cochabamba and close to 200 in Bolivia), with similar events going on in La Paz and Santa Cruz at the same time.
