It helps small groups to communicate more frequently, more easily, and more accurately. Effective communication improves the efficiency, productivity, and coordination for the group and for its individuals.

- IMs, chats, e-mail, twitter: provides easy direct communication between one or many people, though it requires good writing and reading skills. It can include attachments or links to multimedia (pictures, video, audio, etc) to enhance communications.
- Collaboration technologies: tools for sharing ideas & information across distances - these let groups to interact when they can (time-delayed or instantly). They allow collaboration using any number of media & file formats.
- Standardization of communication formats: the use of common standardized document types (e.g. .doc and .xls formats) and common software that can read/write in these formats lets us easily communicate complex notions.
