Luis Villa revisited criticisms of OpenOffice.org after two years, and recently posted What OpenOffice.org is Still Doing Wrong. His thesis is that Firefox, rising from the ashes of Mozilla (okay, maybe not phrased that strongly, but I like the image), represents a better strategy for making usable and easily adoptable software.

Of course, feature-for-feature compatibility seems like an obvious goal, but reducing the technical debt of a project almost always pays off.
