I'm talking about in your no advertising world not now. Sure people can make amazing sites but they need time to add to them to get them to a point where somebody would be willing to pay a subscription fee. Advertising provides that income for these people to be able to juggle both. Not to mention the fact that people have limited amounts of money. If i had to pay a subscription fee for every site i went on i would be skint!
But that's just it... most 'big' sites are for companies who can afford to pay for the groundwork. Other 'interesting' sites are academic or personal, which don't necessarily need subscription and can be free because the costs aren't really huge.
The internet was full of interesting and useful sites around 1998... and there was far less advertising. In fact, going back to BBSs, all the main 'sites' were subscription based and there were many free hobbiest and academic 'sites' as well. It worked fine back then.
I suppose that everything is so cheap these days and everything is expected to be free, that people perhaps don't see things the same way... and yet I'm supposed to just put up with advertising being forced upon me ?
