Information wants to be expensive?

After looking at the cost of the notes for the first Semantic Web Conference I thought I would use Google to route around the 56,00 Euros that it cost. Is it ironic that a conference on making information more accessible is hidden behind a torturous e-commerce system? Anyway I did a little googling and found most of the papers here's a quick attempt:
