Just be carefull where you expose yourself. If you don't really have much to hide then you do not need to worry all that much.

The internet is not the safest place to put personal information on for others to look into.

I bet the new generation has a totally different mindset since they do not know better then that there is internet. They can not
imagine a world without it. But a bit older people have awareness of when the television got introduced and later the birth of the internet.
