As regular readers know, I'm huge on nonprofits using their technology to do more mission. This ranges from better websites, to using web 2.0, to better marketing materials, and on and on.
Such use demands good planning, synching the IT needs of the organization with mission, vision and strategic planning. Even though the cost of tech is down, it's not free, by any means. So, good stewardship requires good planning
