Growing an infrastructure: the role of gateway organizations in cultivating new communities of users

Issues of scaling are critical when an infrastructure is trying to grow. Systems that worked well with smaller numbers or particular types of users must change to meet the needs of an expanding and diversified user base. A first step toward growth is to cultivate new users. We present results from research that examines one approach to the challenge of attracting new users to a large-scale computing infrastructure. We describe gateway organizations and the important social and technical support they provide, which help potential users to conceptualize a use for the infrastructure and increase their willingness and ability to use it.
