SOCIAL NETWORKS Social networks could be useful for little companies, it is a way to become known. And, It could be a marketing tool. But they have another sides that don't please me. Especially the fact that a lot of people spread their life on social networks while another spy them, I call that unhealthy curiosity. Everything that is published stays for ever on line, and these, could be reappear at any time in another form or context. Furthermore, some people use social network to settle accounts. Putting someone down in writing is easier and more hurtful than saying it to his face. On the other hand, social networks could be dangerous for children, some people up to no good hide behind a false profile to abuse them. It also exists cyber harassment that could have disastrous consequences on a weak person. Today social networks are inavitable, but should be used with moderation, excessive use could conduct to an addiction.
