I just joined Technorati because I've read about it on other blogs. I don't fully understand what it is, but I'm willing to dive in and see what happens with that.
Today I tried using an online survey with my classes, but I think that I accidentally locked it so none of their responses could register. I reassured my classes that the real point was to just get them thinking about their responses, but we couldn't help but be disappointed. I have to find better ways to set up new uses of technology and check for loop holes before trying something new in class.
