  In a previous Letter (cond-mat/0106565), Goh et al have presented a numerical
study of the load--or betweenness centrality--distribution in a scale-free
network whose degree distribution follows a power law with a tunable exponent
$\gamma$. They showed that the load $\ell$ is distributed according to a
power-law with exponent $\delta$. The authors claimed that $\delta$ is
universal, ie. independent of the exponent $\gamma$. In this comment, we use
two different ways of checking numerically this universality and we show that
it does not hold.
