Re: There is only one way.
I see you have a rosy view of humanity and their common sense. My view is that as folk become accustomed to the web, they become less, rather than more careful and the problem will creep back up.
I don't normally draw parallels, but in this case it illustrates my point nicely. The AIDS epidemic gave people a certain amount of pause when it came to high-risk activities (you know what they are...) because AIDS was scary and fatal. As time went on, the initial infected died off, and treatments improved to the stage where surviving an infection is certain (at least in the UK, where healthcare is free) as long as you keep taking the drugs. People gradually stopped being careful and now we have a syphilis epidemic amongst teenagers in Scotland.
Moral: as long as people send you links and/or offer "safe" sex people will forget the lessons of the past and will indulge in unsafe practises.
PS: taking anti-retrovirals to survive is NOT nice. And the other STDs, GC and syph, are becoming more drug resistant daily. BE CAREFUL!!
