Freemium BUNDLR allows users to clip and organize web content individually or collaboratively to create rich multimedia collections. Bundles are created by embedding content from YouTube, Vimeo, and Pinterest or any of nearly 200 other web content providers. There's also a nifty browser plugin that allows users to clip a specific image or text selection from any website. It's similar to Pearl Trees or Instapaper but the UI is a bit more robust and the bundles themselves can act as web artifacts -- they're easy to share or embed on other sites. All bundles are public unless you're willing to fork over $20/year.
