It would be a useful and easy to implement idea to create a measure of reciprocity. In it's basic form, it's the %age of reciprocal ties in a network. Can also be calculated for an individual actor/node (%age of reciprocal ties/links of all the
ties the node has).
There are many measures for reciprocity, but the simple one can be enough. More advance measures, can take into account strength of ties.
