Various studies have shown that informal communication is crucial for creative work groups, such as research and technological development teams. This applies not only to the well-being of the group but also to its efficiency and productivity ( Kraut and Streeter 1995). Especially in the negotiation phases of forthcoming projects the frequency of informal communication acts is very high and consolidates the later cooperation ( Finholt, Sproull and Kiesler 1990).

Among those are the VideoWindow ( Fish, Kraut, Root and Rice 1992), the Cruiser ( Root 1988), the Polyscope system ( Borning and Travers 1991), the Electronic Agora ( Travis 1995), the FreeWalk system ( Nakanishi, Yoshida, Nishimura and Ishida 1996), Piazza ( Isaacs, Tang and Morris 1996), etc.
