I think that Google is becoming a more useful PKM tool than all of the KM initiatives of the past 10 years combined. Individuals now have a wide range of very powerful and cheap tools available, but they are blocked by either their IT departments or their own lack of understanding. I am trying to address the latter issue

The good news here is that the users (individuals) have a critical mass on their side, or it's probably shaping up to be that way.

If they keep on using it (those tools and services) it will become something that grows by virtue of familiarity and demand, aided and abetted by yours and others efforts ... no ?
