Oh, be careful, little hands, what you type...

Young people often behave in foolish and uncritical ways, but it's even more foolish and uncritical to blog about it.

Millions of young people could damage their future careers with the details about themselves they post on social networking websites, a watchdog warns.

The Information Commissioner's Office found more than half of those asked made most of their information public.

Some 71% of 2,000 14 to 21-year-olds said they would not want colleges or employers to do a web search on them before they had removed some material.

The commission said the young needed to be aware of their electronic footprint.

It seems the electronic footprint can be more dangerous than the carbon footprint. The more details you give, the more likely someone will take advantage of you.

Let's be careful out there.
