OpenOffice.org may not be the number one free alternative to Microsoft Office for much longer. Since Oracle acquired Sun the future of the open source office suite has been uncertain. So uncertain in fact that a group decided to fork the code base and create an alternative implementation called LibreOffice under a new organization known as The Document Foundation.
Essentially LibreOffice is the equivalent of OpenOffice.org, but in no way is under the control of Oracle. The Document Foundation asked Oracle to come on board and to allow them to use the OpenOffice.org name. Oracle refused and asked anyone associated with LibreOffice to leave the OpenOffice.org project due to a conflict of interest.
