The founders of social test-preparation startup Grockit plan to reconfigure online content such as YouTube videos, Wikipedia entries, and e-books into ordered lesson plans. Their new product, Learnist, works a bit like a Pinterest for learning–users compile content pieces onto a board (or “learning”), suggesting a path in which other users may consume each content component. Learners can check off each component as they go or “re-add” it to one of their own learnings.
