Devshop (http://devshop.com) is helping us keep our project on task and understand where our distractions are coming from. If someone wants to unfreeze requirements they know it's their fault we're not going to meet the schedule.

Basecamp is basic. 37s develops simple apps for a mass market of simple needs. If you exceed the need for simple you have to find something else. Since your here you're probably not that simple. ;-)
