Reading the version 2.0 I would like to comment on the definition given in first page.

Just after Papadimitriou citation  (3rd paragraph page first)  I believe it will be nice to shift

the focus on the WWW and services rather than Internet (physical layer)

I would add something like

“Even more the whole hierarchy of systems defined on the Internet layer as the WWW and social networks on it,

create a complex and intertwingled web of networks whose mathematical properties are still unknown at the moment.”
