First off, Todd Sharp has just released slidesix, which he describes in more detail here. It is a presentation hosting service built in ColdFusion (with Model-Glue FTW!). One of the coolest features is that you can record audio for a slideshow directly on the site.
Secondly - NIN has released this second new single, also for free. This time they used Facebook. You can download it here. As I’m in the middle of Mark Madenl’s Transfer presentation, I haven’t played it yet, but the first free track was pretty darn good.
