Trend: Use of Statistical Physics in studying the Internet and other networks

In re: Evolution and Structure of the Internet: A Statistical Physics Approach by Romualdo Pastor-Satorras and Alessandro Vespignani (Cambridge University Press, 2004).
This is one of a series of recent articles applying statistical physics to the internet and network theory. So, asking a question, is this appropriate? There's not enough information on this page to really make a decision. In the past few years statistical physics has been applied to biology and other problems. Some of this has been jumping on the biotech bandwagon and some has been really good work. What do you think?
