Originally, I thought this thread was concentrating on reliability. As folks are apparently including the standard use product moment, might I suggest that those that haven't read Jacob Cohen's book on power analysis take a look at chapter 4. It offers a good discussion on effect sizes and gives what I believe is still the most respected criteria for small, medium, and large effects.

Cohen, J. (1988). Statistical power analysis for the behavioral sciences (2nd). LEA. Chapter four runs from pp. 109 to 143.
