New Diigo Lists for Math, Science, Social Science

I've added three subject-specific lists on Diigo, to share resources that I find that are relevant only to certain teachers.

• Math:  www.diigo.com/list/kfairchild/math
• Science:  www.diigo.com/list/kfairchild/science
• Social Science:  www.diigo.com/list/kfairchild/social-science

I'll add to these lists throughout the year; I'll continue to add to the general EdTech list (www.diigo.com/list/kfairchild/ed_tech); and I'll add other discipline-specific lists in the near future.
