The internet has been a great thing for the free flow of information and can be very positive. However, there are also a lot of negatives. It is things like this England's EBay for Sex that make me understand the Charedi viewpoint of banning the internet.
In the case of the internet, I believe that the ban will fail, it is something that simply cannot be stopped. There are too much useful things to ban it. However, we need to understand the problems and figure out a way to deal with them intelligently without either ignoring the problem or becoming like the Amish. There is no easy solution, however, we need to keep in mind that while it may be a good thing to be open minded, you can't be so open minded that your brains fall out.
