The absence of concrete results on Artin's conjecture is amazing. According to Wikipedia there is not even one integer N for which it is known that N is a primitive root modulo p for infinitely many primes p. Not even N = 2. Amazing. --Dan << And that is devastating because (pathetically!) it is not even known that 10 is a prim-root modulo more than a finite set of primes: http://en.wikipedia.org/wiki/Artin's_conjecture_on_primitive_roots
