Could you explain how Saaave makes bookmarking more organized? Few weeks ago I've written on HN about my side project LStack (http://lstack.com http://lstack.com), which essentially is also about better organization of bookmarks. It features bookmark parameters (like - price:100 USD, type:webapp, genre:jazz), powerful filtering and organizing bookmarks into groups and folders (I call them "streams"). How would you compare LStack to Saaave? What are the differences and / or similarities?
