Social Network Sites vs. Social Networking vs. Network-Based Tool

My head is being thrown for a whirlwind as I try to catch up on some posts from Danah Boyd on apophenia.  In this post, Danah talks about the difference between Social Network Sites and Social Networking Sites.

I think she basically says the difference between Network versus Networking is whether the relationship is initiated online or not.  Networking implies new relationships are being made, while Network implies a reflection of existing relationships. I believe most sites (Yelp, Flickr, Facebook, Myspace, Twitter) are a combination of both existing relationships and those relationships made online.

I like this definition:

Social Networking sites are “any network-based tool that allows for community creation and content sharing” -Harkness

I just want to make sure I use the correct words when I communicate my project to others. Since I intend to look at the connections Israelis make with others abroad, be it from their travels or simply through social networking sites.
