Just one little tweet for Larry Ferlazzo, but a great leap for EFL teacherkind:
There is a great new wiki set up by Joyce Valenza, a Library Information Specialist in Pennsylvania, containing a wonderful collection of links to tools currently available for free to use in education. This is clearly not the first, many people have put together great collections, but this is the one I find most accessible to a relative beginner.
It's all here, from tools for photo editing and podcasting and getting your ideas organized and visualized to building social networks. This latter point is really the one I would most warmly recommend you start looking into. I sometimes worry that my dear colleagues are missing the boat. This wiki, with its inviting front page, might just do the trick.
