I'm all in favour of banning children from access to any form of social networking site online.

Social networking sites can not only put children at risk of predators, but content on social networking sites contains a mixture of useful and very bad information.

Not all social networking sites are bad - but I have no objection to even perlmonks being restricted to children whilst at school.

There's nothing wrong with doing what I did when at school: go visit a library and read technical magazines or non-fiction books.
