I just noticed Just Tweet It – The Directory for Twitter Users.
Add your name to the directory or search for other educational (or other) Tweeters here.
iLeonardo looks like a promising social research tool. The “about” page describes iLeonardo as “a Social Utility for connecting to people and their collections of relevant information on the web.” Using a bookmarklet, you can find and clip text, image links, and URLs, and store them in “notebooks”. Or you can find other people who have created similar notebooks and browse and copy from theirs, or collaborate. The tool seems like a cross between Delicious and Google Notebook.
This video may give you a better idea of how it works:
The service is seems to be in a closed beta right now. You can request an account, or let me know and it seems that I can send you an invite.
Flowgram is a nice tool that I think many educators would find useful. Flowgram allows you to take webpages, photos, or PowerPoint presentations, put them into a linear sequence and add audio narration and notes. The result is somewhat like a screencast. It is free, does not require a download, and Flowgrams are embeddable in your blog, or can be shared in other ways (e.g., Facebook, Delicious, etc.)
Abhay Parekh, founder of the company, created a Flowgram to demonstrate the capabilities of the tool. Click on the image below:
Flowgram may be useful to yourself, or students. I can think of a number of educational applications.
