I think the next killer apps will consist of software that is gradually opened up as the user becomes more familiar with it. You can take this approach with anything, but I love the fact that the writer referenced to video games. Heck, there is a LOT from video games we can learn like a point system. If you want a great example, look at www.thesixtyone.com (I am not behind that, but I am familiar with who created it, former guys who worked at Electronic Arts). You can make the most complex software work for the simplest every day person if you open it up gradually. Why do I have all of the crap that currently exists in Microsoft Word if I don't even need it? Arguably, this is why there is so much hype around products such as Basecamp that are a world simpler than the current products that exist. We're trying to build 1 product to accomodate 100% of its users.
