Although Pageflakes is not the normal web site I have that is a tool to use or do something on it I included it in this site because I thought it would be good for students to see how they can set up a search engine page that is unique to them alone. Google is great, don't get me wrong, but Pageflakes is like the personal google that you can make, just more canadian. You have to register and you do get an email verification - that's fairly fast, depending on how busy they are that day. But play with it before you let the kids try it and see all the options that are there. This makes a great discussion for students to see how you can hook all social tools together.
By the way, in the end pageflakes uses google to search.... Imagine that ;)
