I love todoMatrix and ideaMatrix very much! I pretty much live and die by it. There was some talk of impactMatrix (similiar to ideaMatrix) but will let you enter in your short/long range goals, so that will be something else to look forward.

My only complaint, I haven't heard from them in some time. Hope that they stop by and give us an update on the next SI release coming up and any other bugs/enhancements to expect.
