I should clarify: Easy to actually pronounce post hoc, but hard to readily discern its correct pronunciation from its spelling (maybe it should be "meow"?).
I wasn't trying to make any ethnocentric points.
Anyway, naming is so important that YC has tons of internal advice that it gives to its companies about choosing the correct name. It's not all that uncommon for a company to get accepted into YC and then immediately change its name.
