I'm not impressed by whatever people read into him. With a real philosopher, you don't have to read in. You can read out. He gives you something to think about that maybe you didn't bring with you.
Interpretations are a dime a dozen. If you take any interpretation of Nietzsche seriously then you're a sucker. He's the Wizard of Oz. On a good day, the man was a flimflam artist. On a bad day, he was simply incoherent. There's no there there. You gaze into the void until you hallucinate whatever happens to be behind your eyeballs.
As the Reverend Stang once said, don't let them pull the wool over your eyes. Pull the wool over your own eyes! At least that way you'll know it's wool!
Total slack!!!
By the way, if anyone is having trouble wrapping his head around the notion of Eternal Return, I recommend The Book of the Subgenius, page 135. Spells it all out quite nicely.
