Social Degree: The social degree of a user is the
number of friendship links in which she takes part. While
the Currensee network is much smaller than many generalpurpose
online social networks, we still expect to see a
power-law distribution for node degree. Figure 1(a) shows the
complementary CDF of the social degree distribution. Most
users in the network have a small number of friendship links,
while a few users have a great number of friendship links. This
distribution can be approximated with a power-law distribution
with exponent 2.6 (for degrees above xmin = 34, fitting error
D = 0.022).
