hello @magicmonk,
it is impressive how many teachers are migrating to social networks, from my point of view it is a wonderful thing that knowledge is no longer only in the classroom but that the information is free and available to everyone.

publicity note:
I'm promoting That curation trail on HIVE and it would help me a lot if you forward it, You can also check it yourself: you might find it interesting to join, I'd love to hear your comments.
