Basically Clipclip is an online version of that: when you find something on the web, you can cut out only the most interesting part preserving the look and feel rather than bookmarking bunch of links. Check it out at http://www.clipclip.org/ to learn more in details.

• Clip - Surf the web, clip the part of any page you want to save.
• Collect - Collect clips instead of links.
• Share - Join groups and share clips with new people.
