xsa, I'm surprised you found the fees of the conference high. They're pretty low for a conference of this type. Nobody has been making money on this either. The organizers are all volunteers and the fees are to actually pay for the costs. Organizing a conference is not cheap nor easy.
We tried to offer a broad selection of talks, over 70 of them on 6 different tracks -- could you be a bit more detailed about the kind of talks you were expecting? The mix of both techie stuff and more business oriented stuff was to me very nice; much more interesting than just one of the two. Please do offer input on our mailing list as we prepare for the next conference.
I believe we had a wireless network set up; don't know whether it was decent or not as I did not try it. Perhaps you could volunteer to help with it next time?
