Cult like adherence to the words of a relatively uneducated man, frequent babbling in pseudo-scientific nonsensical terms. 'reinventing the wheel' and trying to claim their knowledge is completely unique and undiscovered (despite the complete opposite). A seeming opposition to mainstream science, and belief in an incredibly dangerous practice (cryonics) that they believe will lead them to a perfect afterlife (replace heaven with singularity and god with AI), and a leader that makes money from sitting around all day taking donations from his 'followers'.

Oh and both Hubbard and Yudkowsky post long rambling author tracts that pretend to be a story....
