"Will the slides be available?"
One great improvement at this year's conference (at least for me)... is the availability of presentations online. It doesn't seem to have captured much "ink", so I thought I'd mention it here.
If you go to the session catalog tool, you can download many of the presentations given (or about to be given!) at this year's conference.
That gets major props from me -- as it really helps the attendee experience. No need to focus on taking notes on what's on the slides and then missing some of the dialogue of the presentation. It will also help people make better choices on which presentations to attend, and not feel so bad when they have to miss one because there's a conflict with another interesting presentation at the same time.
And as an even bigger benefit, it enables developers around the world who weren't able to make it to this year's conference to see what's being presented.
Nice add :-)
