Some thoughts from last year.
The keynote on encryption was "meh" - did not like the speaker. Kept going on about his books and achievements, really I would have preferred more stall time or chatting to people.
I know all conferences do it but please stop advertising for next year. Let me enjoy this year, I don't care about your in-conference rate that expires at midnight. Let me have my in-conference rate for 2 weeks and I'll decide then.
Some stall holders were just grumpy, disinterested. I don't get why they were there. One of them when I tried talking to them said "We sell storage systems for the 50k mark, so mainly enterprises" - But you are at a heavy duty SMB focused event?
I think a lot of the "user" talks are very thin. Not enough meat, felt like they did it for the free conference pass as opposed adding value to the event.
