It's not like we didn't know this. But it appears to be a case of the reality growing to meet the perception, rather than the other way around.
I get a LOT of questions from folks who want me to set them or their parents up with a computer and Internet access in such a way to allay all their fears. So far, I have demurred in most cases. I don't want to be responsible for whether or not someone sleeps peacefully at night. But I am devising a solution, which involves using a Linux or Mac OS X machine and some fairly restrictive browser settings. Yes, I know that is not a guarantee of security and that nothing really is, but it should help. Especially if combined with some common sense rules of conduct.
More on this later.
