That's not really the geometric interpretation of the Riemann zeta function, but rather the series \sum_{k=1}^\infty 1/k^n. Riemann zeta function makes sense not only in positive integers greater than 1, but also on the almost whole complex plane, and identifying complex zeros of zeta function is of main interest.

Okay, so it's an interpretation of Riemann zeta on positive real integers. It's still neat. ;)
