We come from a different background. I have been fascinated with the
structure in aggregated journal-journal citation relations. These are large
networks with fine structures which are reproduced from year to year.
Stability is prevailing and change the exception. For example, I have tried
to measure areas of change using probabilistic entropy measures: where is
the network "hot"?
In other domains, there may also be more stability than one thinks if one
chooses a more abstract unit of analysis--or, perhaps better, a unit of
operation. If one looks at variation in relations, one cannot find the
patterns. Otherwise, we agree about the hypothetical nature of the various
measures for change, structure, and stability.

> 15 Assertions about the Philosophy and Future of SNA
> 1. Networks are a form of classification method. Membership

> natural networks just as philosophers have found no natural
> 1A. The primary purpose of SNA is to create discrete bounded sets.
> 2. The underlying premises of SNA in establishing sets are
> dichotomies between linkage and actor and between actor and
> context. These dichotomies were theorized to enable discrete
> mathematics to be applied to networks in the form of
> measurements. They also followed cybernetic models that
> simplified computing networks.
> 3. Measures (e.g. centeredness) are expressions of relationships
> (ontologies) made from a given perspective. Because the
> underlying data is constructed, the measures are constructed.
> This is not an assertion
> that they are useless--only that they are cultural.
> 4. Stability and consistency are the primary problems of
> network membership because the hoped-for structure is
> non-existent. Systems are not predictable and membership in
> classification schemes is problematic.
> 5. Assertions about lasting stability refer to "structure."
> For structure to exist there would need to be stable
> 6. The problems experienced with stability of membership (or
> relationships) are quite similar to those previously found in
> 7. The standard response to such problems (hoping to maintain discrete
> sets) would be probabilistic memberships.
> 8. The response after this one is typically to look into how
> cultures evolve (e.g. the Boyd and
> Richardson/Bowles/Bienhocker, Gunderson and Hollingesque
> Panarchy and other Santa Fe sorts of works). The result is a
> turn to "complexity studies" where cycles and long-term
> trends are sought in the evolution of "structures."
> 9. Increasingly there is a crisis between stability
> (structure) and change (innovation) where innovation is the
