The idea that we are sufficiently different from other chimps as to have our own genus is perhaps even more lacking in humility than the 'sapiens' tag.
I agree with Pratchett et al. that genus 'Pan' should include us and our immediate ancestors. Although I guess we could equally well promote chimps to Homo Troglodytes, but then 'Homo Paniscus' would become rather odd, so Bonoboes would need to become Homo Homunculus or something.
It's easier just to move us to Pan, and either call us Pan Sapiens for backward consistency, or perhaps Pan Falsus, given our joyful dissemination not just of stories, but of outright lies.
