I am very impressed with bubble.us. I think this is a great way to brainstorm new ideas and other information with colleagues and friends. In addition, Bloglines is a great tool that can be used to find many useful websites and blogs. I see Bloglines being really useful for learning about all sorts of information on many subjects. I also think that Thinkfree mobile is another useful tool. Thinkfree mobile allows you to edit and share messages directly from a smart phone. I think this is important because sometimes you may have a smart phone, and not have access to a laptop and this could be a very useful technology for sharing important educational material.
