EDMODO FOR ALL: Edmodo's growth has looked something like that hockey stick shape so beloved by investors. (User stats: founded 2008; by September 2010 it had reached 500,000 users; today 7.7 million, of which about 700,000 are teachers). Now the company aims to rev the engine, hoping to reach 1 million teachers by September. Key to growth has been passionate teachers--and part of what has won their loyalty has been an exceptionally responsive support desk. So how will they keep support strong while growing user count? Turn the most loyal users into part of the support program. Beginning in July, Edmodo will start designating some power users as "Edmodo Ambassadors." Andromeda Abushady, director of operations, says that Edmodo will carefully review the track record of potential Ambassadors, looking for teachers who are both experienced Edmodo users and are recognized in their schools for leading professional development and helping others. At least for now, Ambassadors will get the equivalent of a red phone into Edmodo as well as recognition and other perks. Edmodo's considered offering pay but is trying to reward loyalty with recognition--rather than seeming like it's just outsourcing its support desk. "No one's trying to do this with superusers so we're treading lightly," Andromeda says. Think you're made of Ambassador stuff?
