blogs and authenticity

I have lots of meetings these days to talk about Social Software (i.e. blogs, wikis, tagging, the web as a stream vs. the web as a library, web 2.0) and about NEXTspace (NEXTspace (d f) our software and often though I have to face saturated people that think they learned everything regarding the web back in the 90s.
The have the feeling that something is changing but on the other side they still cling to the world they know.
It’s difficult for them to understand what it means if people have conversations (t d f) on the web. They complain about trustworthiness (t d f), authenticity (t d f), and truth forgetting about the problem of truth (t d f) alltogether.
We all feel nonetheless that something is changing.
