I disagree with their interpretation of users having "a greater number of distinct friend communities" as signifying something as simple as "diversity" (see hypothesis #7). While it's related to diversity, it's more of a measure of how cliquey and/or segregated the user's different community groups are, and might even be thought of as a measure of segregation in the user's social environment. Funny that the word "diversity" would be used for this.
