Facebook & Social Capital

For those of you who read "Connection Strategies: Social Capital Implications of Facebook-enabled Communication Practices" I think we can all agree that it was very interesting. I found myself reflecting  on my own Facebook usage and how it correlated with what the study suggested. I can certainly agree that the amount of friends one has on this site makes a difference. Whether said friends be close or just acquaintances, having a numerous amount increases both the bonding and bridging of social capital. For example, by having a higher friend count, each status or photo posted is more likely to receive feedback. With close friends, this feedback may be more personal and emotional, therefore helping to bond social capital. As for acquaintances, feedback is likely to be less personal and emotional, but can still help to bridge social capital by "breaking the ice" in a way. It establishes a common ground and possibly will increase the chances of contact offline. This often has been the case for my Facebook experiences. The study goes far more in depth on the topic, but I felt as though I or someone I know could relate. How has Facebook affected social capital in your opinion?
