Just the portions of interest

How many times we surf the net and wish to cut a small portion of text / information and retain for future. We normally bookmark them in our browser or better in tagging services like Del.icio.us. Today I came to know that there are tools that are meant exactly for "marking" portions of the sites of interest. Clipmarks and Net Snippets are one I am talking about. On first impression Clipmarks
seems to be a better choice as it being a "hosted" service and thus you are not bound with your Desktop. Later found out that Net Snippets will also do the same by uploading the collection. Both tools can be integrated with my favorite Firefox.
