"It's better to structure information according to how people use it, rather
than what department owns it"[Jakob Nielsen 2009]

enterprise 2.0
"the use of emergent social software platforms within companies, or between companies and their partners or customers" [Mc Afee 2006]

"emergent social software platforms"
"digital environments in which contributions and interactions" are:
• "globally visible and persistent over time"• performed with social softwares that "enable people
to rendezvous, connect or collaborate through computer-mediated communication and to form online communities"
• emergent, freeform, with "patterns and structure inherent in people’s interactions".
[Mc Afee 2009]
