Power law distributions of number of days dij, where individual i interacted with individual j. These results were similar to those of previous studies (Hossmann et al., 2011; Hu et al., 2012; Arnaboldi et al., 2012; Song et al., 2012; Fujihara and Miwa, 2014). Power law coefficients were 1.92 (a: Twitter), 3.71 (b: 755 group chat), 2.29 (c: 755 wall communication), 1.97 (d: Ameba Pigg), 1.98 (e: mobile phone) and 2.00 (f: SMS).
