It's just a general category for people who think that his epistemic perspectivism is fundamental. So it's broad and many of the people who I categorize there don't agree with each other at all. I was thinking of Judith Butler here but there are grounds to disagree with my characterization.
Nehamas' project was to explain Nietzsche under his notion of "Aestheticism". I don't think I can explain it very well here, but Nehamas' is one of the most significant Nietzsche interpretations right now. If you're interested I'd recommend reading "Nietzsche: Life as Literature". Maybe the basic idea is something like: "Literature offers an interpretive framework to reconcile the contradictions in Nietzsche" and the reconciliation basically functions by rejecting the idea that there is any foundational truth in Nietzsche. It's more like a collection of interpretations.
The Kaufmann experimentalism approach, which is still fairly popular (I think I remember a professor from Sacred Heart championing this for a while), is opposed to the perspectivism approach on the grounds that experimentalism believes Nietzsche's perspectivism is a tool to better capture a foundational truth. In this respect the perspectivists think that there is no 'truth' in Nietzsche's project, all truth collapses into interpretation (or perspectives) where as the experimentalists think that Nietzsche believes in a foundational truth (or at least the possibility of one) but is trying to better capture truth with perspectivism.
