Samuel Kordik recently cited Backpack as his website of the week (this was before the recent Backpack Multiuser launch).
He says he uses Backpack "to run my life...I use a page for each of my action lists, and then a page for projects, a page for Someday/Maybe’s, and a page for Notes." Here's more:
Backpack is an amazing website/service from the innovative startup 37signals. It is essentially a web-based productivity/organizational tool. It is slick, flexible, and super-cool. In fact, it combines the total flexibility of a paper-based notebook with the infinite re-writable possibilities of electronic data.Built using the flexible power of Ruby on Rails, Backpack is one of those no-brainer tools that hides mindblowing capabilities. It actually significantly reminds me of an Apple application. It just makes sense...
What do I use Backpack for? To run my life. At this point in my life, it makes sense to have things online. I have internet at work and in my room, and so it provides a handy central point to run things through.
I use a page for each of my action lists, and then a page for projects, a page for Someday/Maybe’s, and a page for Notes. This flexible solution works quite well for me.

Do you use a 37signals product in an interesting or noteworthy way? Let us know.
