MiddleSpot is a new tool that lets you create a learning environment by combining different elements: websites, music, videos, text, embedded gadgets, your own html code, images and even attached files. Once you have created a mashup (a workspace with a combination of resources), you simply share it. You can email it, embed it or even share via Facebook, Twitter, or other social sites.
MiddleSpot is one of those tools that is really intuitive so you can have an environment up and running very quickly. Again, a great tool to combine with a blog or wiki if you already use those tools.
