When joining a social network, the already well-connected often make for especially attractive partners because they can facilitate links to other network members. However, the effect is potentially weakened by increasing redundancy of contacts with network size. We consider the trade-off between these two factors in a dataset of the Cambridge High-Tech Cluster and compare results with the county of Cambridgeshire as a whole. As expected, network effects are stronger in the former, but in both datasets, redundancy does not offset the benefits of reach in attracting new partners.
