Gnomer (and Novell employee), Michael Meeks, provides some great insight into the health and viability of the Open Office project. A complex wonder of engineering (supporting .doc in some cases better than Word) while also supporting open standards, Open Office is arguably one of the most important pieces of software out there. It's indispensable for Linux freetards, and quite useful on Mac and Windows as well. Any commercial company thinking throwing code over the fence is "open sourcing", should think again and read Michael's conclusion.
