Nietzsche is referenced constantly:

Also, some pretty substantial continental philosophers wrote about Nietzsche. Heidegger wrote a ton about him. Foucault used his genealogical method. Deleuze, Derrida, etc. all wrote a lot.

Heck, half of the big Continental names wrote books on Nietzsche:

Analytic philosophy indeed didn't write much about Nietzsche, but I don't know why they would have. Very different subject matter and style.
