Mixer Publishing states "We offer a 50/50 split of royalties with the author". The only problem with that is that royalties are by defintion the "amount of money that is paid to the original creator of a product". So any publisher can really only ever pay a writer 100% of their "royalty". This leaves prospective authors playing the now familiar game of trying to work out what, exactly, they would be getting 50% of, and I bet it ain't the cover price.
As for being "post genre", they do not seem to be post-post-modern which is arguable more passé these days. Recommended for writers who use worlds like dialogical, epistemology, and 'affirmative humanist ideology' in everyday conversation. They do seem to want erotica, but beyond that... I will need a translation from someone who speaks the verbose lingo of those that dwell in the land Focault forgot.
