This is a spin-off idea from Brett B's post on a Teachers University
So what if there were an open source resource where teachers share Professional Learning experiences, information, videos, activities, research, etc...
Each resource would be posted, edited, revised, shared, manipulated, built upon, and maintained by a volunteer community of educators - and access would be completely free.
Tags could be applied to each resource to make searching for a highly specific piece of information easier - for example finding a K-5 appropriate approach to teaching "Computational Thinking" for English language learners - or something to that effect.
The site could also host regularly scheduled on-line chats with moderators to answer questions, or instead provide a video message board function where participants send pre-recorded questions to the community and received recorded responses in return.
A ranking system could also be applied that allows extremely relevant or impactfull learning experiences to stand out, or be sorted.
