friend harvesting

This is the practice of amassing large numbers of virtual "friends" via Facebook or Cheezburger.com or some other social network site. The actual friend harvester may have far more of these virtual friends than he or she has familiarity with of the time to interact with.

Surely Meredith is engaging in friend harvesting, she has amassed a collection of 1050 "friends." I wonder how many has she known personally?
