Two types of electronic brainwriting are used typically in Group Support Systems research: poolwriting and gallery writing. While a large number of academic studies have used the former technique, the latter is more efficient and effective, but has been used less frequently.

An experiment using the two brainwriting techniques shows that subjects were more satisfied with and preferred gallery writing. In addition, subjects using poolwriting were able to see only about 50% of the comments generated in the electronic meeting, while gallery writing subjects were able to view all comments
