Which Web 2.0 tools are available for use in an office environment?
I’d endorse everything that Rod suggested, but as well as SocialText as an Enterprise class wiki, you might also consider JotSpot, or Confluence from Atlassian. You should also take a look at the whole family of Web 2.0 office tools that are being discussed at next week’s Office 2.0 Conference that Rod and I are attending next week in San Francisco. Take a look at ITRedux’s Office 2.0 database for a complete range of the available applications and web services.
