One of the skills expected from a CEO is initiative. PersonThe person who would fit as a CEOapplies for the position is expected to know how to contact Stack Exchange and present themselves in athe proper way.
That's why, to my understanding, they don'tStack Exchange didn't post a direct form, which would likelyhave only causeled to hundreds of joke/unfittingunsuitable submissions, and it will just waste lots of time towasted SE staff who will need to wadestaff's time by wading through it all.
So yes, they lookthey're looking for a new CEO. They want only the best of the best to apply. Good luck! :)
