You don't need the scroll wheel to navigate the presentation. Click on the right side of the slide to go forward, on the left side to go back.

> Honestly, who thinks this stuff is a good idea?

People who are making presentations to deliver in an in-person setting where putting them on the web for everyone is a secondary use, not the primary use? I mean, looking at that, it would be a lot better as the visual component of an in-person presentation than it is on its own (though its not without value on its own.)

I think it's a good idea, btw :-)

You can run code on your slides, check http://talks.golang.org/2012/concurrency.slide#14
