I'm very interested in collaboration technologies. I found an interesting tool at a small company in Canada called SilverOrange, www.silverorange.com, who have a nice web-based collaboration environment. I really like the interface and while I was searching for more of a traditional project management system, there system probably fits my somewhat "loose" style of management.

Items are based on projects, but the information is more like an on-going conversation between team members. Lots of features. I will be testing it out for the next few weeks.
