Internet Usage Statistics Wanted.
 

I am looking for quotable statistics of:

1. Number of children online and how many have been solicited for sex.

2. Statistics related to number of people that flirt online and also hookup because of it. (and related statistics, i.e. cheating, phone contact etc.)

3. Statistics of internet activity/usage of people at work.

Thanks for the resources if you know of any. Back to google for more hunting.
