I have over 3,000 webpages and over 2000 links saved and organized in Scrapbook. Scrapbook can recursively safe entire websites. Searching for good information is tedious with search engines. Webpages come and go. Scrapbook lets you build a library, your own personal knowledgeable over years. You can highlight text and save the results, too. All the webpages can be be organized in a tree-like hierarchal manner.
The only issue with it has to do with synchronization and differential backups. It should be rewritten to save Mozilla Archive Format files MAFF's so that synchronization would be quicker from machine to machine.
Just don't use Scrapbook on Slashdot. I got banned from Slashdot several times, because I wanted to save a single article to read while taking transit home. I once got my entire office banned from Slashdot.
