While we've featured similar tools in the past (like ScrapBook), Clipmarks is a tool that saves snippets of web pages that has the distinction of storing them online. While there's danger inherent in trusting services that keep your data on a remote server, Clipmarks's value exceeds (for some) that of ScrapBook and others because it's a social service. Like del.icio.us or other social bookmarking sites, you can make your Clipmarks public and you can search others' clippings. In order to "clip" web sites you have to install a Firefox extension which you can use in a number of ways. Check out the demo on the Clipmarks to get a better idea of how it works.
