Query: A note on "Weighted Evolving Networks: Coupling Topology and Weight
  Dynamics"   We discuss a newly proposed model by Barrat et al. (Phys. Rev. Lett. 92,
228701, 2004) for weighted evolving networks and suggest yet another model
which can be viewed in the framework of worldwide airport network as "busy
airports get busier".
