We no longer link to nor use facebook. In spite of the fact that it is highly recommended for orgs to have facebook pages because facebook is so 'popular', facebook is also an extremely bad influence on the internet, disrespects its users and their privacy.
The founder has called his users 'dumb f**ks', and there are numerous other scandals. If we want a better world, then supporting things like facebook and its founder are counter to that aim. The site itself is designed to produce mindless gossip and it is difficult to use it for anything constructive anyway. It's puerile and is breeding a whole new generation of narcissitic people incapable of real communication.
