Here's a few 'web2.0/techie/learning' links that have been lurking in my bookmarks folder:
Alternate reality games, Facebook, Wii, Lecture Capture, Google Apps, Skype, Wikipedia, Creative Commons, Ebooks, Screencasting and so on. The pdfs are visually appealing and quite thorough.
Written for school library media centres, this wiki is full of easy to understand tutorials and tons of great links to check out for doing web stuff like blogging, social networking, photosharing and so on.
A fantastic, highly visual tool useful for explaining Boolean searching. Try it out, it's kinda fun to play with.
