Last weekend I gave a presentation to the Twin Cities Code Camp about Electron called:
How I Learned to Stop Worrying about Cross-Platform and Love Electron
It went pretty well I think, there was more content than time permitted me to go through but for the most part the presentation went along smoothly. I made a kind of interactive demo / tutorial application in Electron that I used to give the presentation, which can be found here:

If you want to play around with electron or use the tutorial yourself to give a presentation feel free! Also please feel free to send a PR if there are any improvements you’d like to see.
