Oracle is providing this wiki so that customers and partners (and anyone else interested in Oracle) can collaboratively create and share content that is helpful to the community at large–whether installation guides and tips, project documentation, technical notes, or anything else (appropriate) that captures your imagination.
Maybe this is the “exciting community-related project” that Justin recently hinted that it was “in the works”.

It is indeed exciting to have an official Oracle wiki and it will be interesting to see how this official wiki will evolve and how the Oracle community will use it.
Update: The name of the wiki has changed from Oracle Whiteboard to Oracle Wiki.
