Good applications of social networks Very often, people misuses social networks available today. For this reason, many critics argue if these systems have any function beyond connecting people to stablish silly conversations. I think we live in an unique, exciting moment in human history, in which people from many countries have access to culturally rich contents. There's a lot to improve, though, specially if we think about digital education issues, since having access to content does not solve the problem of interpreting content. Education is not my point now, but I would like to share an insightful Ken Robinson's video about the subject: http://www.ted.com/talks/ken_robinson_says_schools_kill_creativity. Another good application of these systems is to political engagement. In Brazil, people are becoming more engaged in debates about democracy. Unfortunately, the dialogs are far from a good level of discussions about ideas and proposals. Extreme people very often "scream" against others with different perspectives, but it is a starting point, at least. To discuss is better than to silence. Besides some distortions, in general, social networks offer much more opportunities than damages for growth.
