> 1488 types whats that?
Chalk this up to 'things I wish I didn't know', but it's a neo-nazi slogan/concept of 'fourteen words' (something about 'saving the future for white children', yada yada) and 'heil hitler' - 'H' being the 8th letter of the alphabet. '1488-types' are a reference to the type of folks who buy into that horsepuckey.
I actually started referring to them this way because of an email from Curtis Yarvin to Milo Y. He was giving Milo advice about dealing with 1488 types in a way that doesn't alienate them as an audience.
