social media: overestimated or not?

it isn't overestimated because everybody uses it and it's faster than the newspaper or even the news. During the strike in Egypt, people knew about it thanks to twitter. After some time twitter, facebook, myspace, etc.. were forbidden because that was the way people got news and kept in conact with each other, so even if newspapers and newsstations didn't work, social media kept people in contact and gave them info about it. also a lot of programs use social media as a form of advertising or keeping people interested in the show (oh oh tirol, american idol, dames in de dop, etc...)
