I'd say that's about right. I've been active on the web (as a webmaster and site-surfer) for over a decade, and while the absolute amount of pr0n has constantly increased, the percentage is about the same as when it was UseNet and there were dirty pictures on the FTP sites.
However the amount of stupid, inane, pointless dreck on the web has similarly skyrocketed, which is what is holding down the pr0n to 1% or so.
In other words, there's a ton of sexually explicit stuff out there, but it's drowning in the meaningless noise, along with nearly everything else.
FreeRepublic is a breath of fresh air, every day.
I agree ,, There is definitely a lot of chaff and clutter out there,, nuggets and oasises are few and far between on the 'net... agreed on FR as well, Unique. to say the least..
