Brainstorming has moved from the individual, to the meeting room, to digital tools, and recently, to online collaborative systems with masses of participants in a “crowdsourced” brainstorm. This paper presents IDEAS2IDEAS, our design of a mass-participation online brainstorming system built to encourage a particular behavior in brainstorm participants: constructive, collaborative ideation. This system (Figure 1) was evaluated against a system built to imitate existing industry practice with a between-subjects study with 60 participants, and found that the I2I system was significantly better at encouraging constructive behavior.
