Instagram in the Classroom?

SEEMS INSTAGRAM CAN BE USED IN THE CLASS.  ACCORDING TO  MARYALENE LAPONSIE, WE LEARN FIVE DIFFERENT WAYS THIS CAN HAPPEN:

1. ASSIGN PHOTO ESSAYS AND PHOTOJOURNALISM
2. CREATE WRITING PROMPTS WITH PHOTOS
3. DOCUMENT SCIENCE EXPERIMENTS AND ART PROJECTS
4. RAISE FUNDS FOR YOUR CLASSROOM OR SCHOOL
5. SHOWCASE CLASSROOM ACTIVITIES AND STUDENT PROGRESS

The funny thing about this is that Instagram need not be the only tool to achieve these goals.  I could just project pictures using any old thing and do the same thing.
