You know quite well by now that some websites are places you shouldn’t go. But if you ask 100 users, 99 of them will shrug and say they don’t go anywhere unsafe.
Yes, ignorance is bliss.
But what tools do we have to judge our degree of trust in a website? Webutation.net is trying to give you one: http://www.webutation.net. They grade sites along several parameters: direct reviews, Google Safebrowsing (sounds like an oxymoron), virus reports, Web of Trust, and child safety or “G” rating.
Amusingly enough, they consider my site quite safe: http://www.webutation.net/go/review/gnorman.org. As always I leave you to make your own judgements.
