The difference between Hi5.com's social-network site for the cellphone screen and those of MySpace and Facebook, CNET points out, is that Hi5's mobile edition 1) "openly targets" people around the world who primarily use mobile phones, not computers, to socialize, and 2) launched in 26 languages. CNET says Facebook and MySpace's mobile editions are designed more as supplements to their Web browser-accessed sites. Point No. 1 above makes particular sense for Hi5's Latin American market, if comScore's international social-networking data is to be believed. ComScore's recently unveiled data showed a 1,055% increase in traffic for Hi5 between June 2007 and this past June. Here's my summary of the comScore report. Here, too, is some context on the growing MoSoSo, or mobile-social-networking, phenomenon from the Christian Science Monitor.
