On the education subreddit I came across 100 Most Inspiring and Innovative Blogs for Educators. It has some good finds, including Jane's E-Learning Pick of the Day. Jane posts small articles with links to interesting online resources. Go look for yourself.
I found a couple of mind mappers I hadn't seen before, and one that a friend had mentioned called The Brain. The video demos look good.
There's also an open-source web-based HTML editor called Amaya I hadn't seen before.
By the way, the neologism "blag" comes from "blog" as an intentional misselling, courtesy of xkcd:
So...log comes from a ship throwing a piece of wood over the side to see how fast it's moving, which comes to mean the book the readings are written in, which comes to mean any form of recording information regularly. Meanwhile "world wide web" gets shorted post haste to "web," and the two words get put together to make "web log," which contracts to "blog" and now (if you're sufficiently geeky and want to be ironic) "blag." Isn't language fun?
