@elbosso Of course you can weigh in! :) I've used reveal.js for several presentations in the past, and I liked it.
The presentations looked great, especially with syntax highlighting.
I did find myself futzing with written HTML more than I wanted though (e.g. wanting an image caption in a specific place). It's also a little harder to share than a hosted service, especially if you want reader comments.
Definitely a great option in many cases still.
