I had a great time at yesterday's online DotNetConf. I think my "Mobile-First Responsive Web Design" talk went pretty well. You can see the talk on YouTube (embedded below). The talk was focused on designing websites to be efficient on mobile platforms by starting with your design on a mobile and scaling up to tablets and desktops.
If you viewed my talk, you might be interested in the slides and source code. You can get them here:
