Wiki....what!?

So, I find myself at the IDC European IT Forum in Paris together with numerous business leaders, IT professionals etc. We just enjoyed the first session, and listening to among other speakers Nicholas Negroponte, founder of MIT Labs and one of the founders of Wired Magazine. He addressed Europe and it's competiveness in creativity and innovation. Talking about the power in free and open source he mentioned wikipedia and asked the audience to raise their hands if ever used Wikipedia. Approximately 15 % did...and I was astonished of being part of such a minority in such a crowd...
