There is no shortage of "Cool New Web Tools" out there and all three of us are guilty as charged for presenting them to teachers via the firehose effect. In our session, we will begin with a nostalgic nod to our presentation past where just 3 years ago we were talking up "Small Pieces Loosely Joined" - blogs, wikis, and a little RSS. Now there is so much more, almost too much. So we may talk about some cool tools, but more at a level of looking at the affordances which make them compelling, and why these and future breeds of tools and platforms matter to K12 teachers.
