@pombredanne You're right - that's why I used the word "similar" and not "equivalent" (i.e., the bulk of the verbiage in this license is copied from the MIT license). That was also just a note to myself on the off-chance I ever felt like using this license for my own projects.
I'd also point out that I didn't come up with this license - you may want to take up any issues with the folks at 37signals or https://github.com/basecamp/fizzy
