interesting...
i'll go along with the general idea that it will get easier to link things and there will be new ways of finding relevant stuff.

but when people say "imagine a world of web X.0" i get suspicious.

I think the problem is, the human brain has certain hardwired limits (that take thousands of years to change) and computers are just too powerful. Also, the last thing I want is to tell my friends exactly where I am all the time, and I probably don't need to tell future employers exactly what I think about politics and religion.

Also, real life is still more interesting, and if you don't lead a real life you end up outputting boring stuff that there's no point linking to. Internet dreamers never really talk about how this stuff gets created in the first place.

Good example: musicians do a great first album, drawn from their whole life experience, and then spend 12 months on the road having no experiences other than the tour bus and some parties, then they write second album, and it sucks a bit.
