After reading Suzanne comments, I went to the MathTools website to view the increase in number of tools reviewed. Cool!
What probably impressed me most about my experience last summer is the attitude of the MathTool staff and other tool developers. They want to improve the existing tools (if needed) and create new resources to fill any existing gaps. For example, Joel used some comments that I made both in person and through a review to modify an existing tool to make it more useful and versatile in the classroom. They want and need our input as educators.
