37Signals boys have been busy - Book and new project management application

This is old, but news to me: 37Signals has released their book Defensive Design for the Web. Congratulations! While "contingency design" might be more accurate, the tie in to defensive driving will help communicate the topic to non-UX geeks.

On another 37Signals note, they've released Basecamp, a web based project management tool that is clean, simple, and effective without all the headaches of Sitespring (Macromedia's discontined foray into the space) or PHPCollab (open source Sitespring attempt). Well done.
