Here's my first Backpack page that I created for a SIG meeting today. It describes how to create a feed from feedless web pages. It's a nice all-in-one page.
Backpack is great for presenting this kind of information and I was quite amazed at how quickly I could produce some nice-looking text modules, reorganize them, and so on.
For speed of page creation though, I like my PBWiki a little better.
