I love having all of these "things" together in Web 2.0 Awards I had never heard of the 2.0 Awards. There is so much to look at! I thought that Upcoming would be useful, maybe not educationally, but personally to look for things to do.
One Sentence could be a great educational tool. After reading it for only a few minutes I felt like I had been through every emotion possible. People contribute their one sentence story to the site, the stories can be searched by tags or date contributed. I thought in the upper grades especially, students could write a book review in one sentence, or a history event, an event in their own life. I don't know if it is human nature or that we have all been taught to expand on most of what we write about but writing anything in one sentence and getting the main idea across would be a huge challenge.
