I have been using Symbaloo for about a year now. I really like it a lot. It is a visual way of sharing bookmarks with other people. The “pages” you create in Symbaloo are called a “webmix”
When I first started using Symbaloo (the education version), they didn’t allow you to embed your webmix anywhere. The only way I could show it on a wiki was to take a snapshot of it using a program like Jing. That was ok, but not ideal.
