the role that vertex attributes might play: If someone is well$-$positioned to bridge multiple groups with distinct resources, then that person may have the ability to leverage those resources as well as to serve as the junction between the groups of people themselves.

How else might vertex attributes inform the identification of opinion leaders? For instance, if someone has very different characteristics from the alters in the network, does that make that person more of an opinion leader or less? What are the implications for bonding and bridging social capital? Likewise, if one of the vertex attributes was some quantitative measure like "money," how would you expect that to affect the emergence and functions of leaders in the network?
