Quite nice solution. I'd use complement myself.

(every? (complement nil?) seq)

Maybe even go so far as define a new function not-nil? In order to make the code express my intention.

@Jesse, indeed. I always forget not-any? since any? doesn't exist. Thanks for pointing that out.

I wonder which is more readable? I can't say I'm a huge fan of either, tho I think not-any? nil? gets a slight nod.

(none? nil? coll) would probably be a bit easier... *shrug*

Another option is: user> (not-any? nil? [1 2 3...

user> (not-any? nil? [1 2 3 4])
true

true
user> (not (some nil? [1 2 nil 4]))
false
user> (not (some nil? [1 false 4]))
true
