I tried last fall is MyLinkCloud. MyLinkCloud just added a couple of important features that are attractive to longtime iGoogle users.
MyLinkCloud now supports RSS feeds. You can display the RSS feeds of your favorite blogs on your MyLinkCloud start pages. The other new feature in MyLinkCloud of note is the option to include search boxes in your start pages. You can include Google, Wikipedia, and YouTube search boxes on your start pages. Normally these features are only unlocked if you invite others to use MyLinkCloud, but if you use the links on this post, MyLinkCloud will waive that requirement for you.
MyLinkCloud continues to support the option to add sticky notes to your start pages as well as the option to create frames or groups of links on your start page.
Watch the video below for some ideas about how your might use MyLinkCloud with students.
