Sooo for $139 I can attend a 5-hour long "conference" with yet-unknown agenda? No, thanks.
To me this looks like a Diligent promotion afternoon for which I would even have to pay a quite high price. Maybe $20-30 would be okay.
I believe having a clear agenda is the step one for publishing a professional conference, as the currently "we are not sure about the agenda, but hey, come and pay the ticket already!" message is obnoxious.
