You know, there are people here who have been working on "Haiku" for fifteen years. There is a company to oversee development, there is a registered domain ... I don't expect to see much enthusiasm for a name change. But let's have a look.
Facebook is three syllables, I believe, and the examples you give are conspicuously not acronyms (Linux was retconned into an acronym "Linux Is Not UniX" after the fact, but that's not how it started out). But if you have to use an acronym, drop the recursive ones. That is just all-too-clever.
