Deathworm, I'll take your word for it that the Internet porn industry was the only one that remained profitable in the early 90s. I seem to recall there were quite a few other survivors but I'm too lazy to look them up
The thing is, the claims that porn is driving technological development on the Internet, and also claims such as yours that "many of the currently used technologies apparently had their debut in areas of porn" have come up here and other places several times. But I've yet to hear of a single actual technology that this clearly applies to, or seen a single RFC that doesn't have either an old hippy or some big IT corporate as the author - bigandbouncy.com and its ilk are notable by their absence.
The IETF is the driving force behind the evolution of the Internet, and that is traditionally a fiercely-policed meritocracy albeit one more recently tainted by the influence of big IT corporations such as Microsoft, Cisco et al. IPv6, the next major "upgrade" for the Internet that the IETF is rolling out, has nothing in its design goals or foundation technologies that I've seen that have got anything even tangentially to do with porn sites.
Sure, most major western corporations such as those that own the backbone links are likely to have mainly men on the board of directors. That's not equality, I know, and it's flat-out not good enough. However, their internal HR practises don't, I contend, have an observable influence on their policies regarding the traffic those backbone links carry. To imply otherwise would be akin to suggesting that the telephone network is sexist because BT only has three or four female board members.
I'm not arguing that all the content or all the users of the Internet is sexism, or any unpleasant -ism, free. It's obviously not. And in that respect it undoubtedly does mirror society; I don't believe I've claimed otherwise.
You can find sexist idiots on the net just as easily as you can find religious bigots or ranting gun-nuts. Kooks of all flavours like the Internet because it gives them a stage from which to proclaim their kookiness. On the plus side, the Internet makes it just as easy to denounce those ridiculous ideas and show others just how nuts these kooks are. It's that equality of access that I see as the key.
