Simple math LL guys and gals. Let's say in a year one instructor brings in and orients 50 higher education students to SL. Let's say 5000 teachers do this. Hmmm, 250,000 well-trained people who have now been introduced to SL, have returned multiple times, and they in turn help build critical mass by brining in friends. Get the point??? We may be better at effectively marketing SL than you. :-)
