The audio seemed a problem as the walk-around mikes never seemed loud enough. The vendor exhibits were mostly worthless and too much time was devoted. Some of the topics I wasn't interested in. Some of the content was too technical for me, but that didn't surprise me. In the morning, you should have a break after 60-90 min.
Attention spans plummet after that.
Perhaps more demonstration of database topics. Sounds were not consistent on the mikes Seating arrangement. Need a stretch break between each presenter. I would have liked more interaction. Do not schedule talks to be longer than 1 hour.
