Ofer Affias sent me a Google Chrome extension named everymark that developed by him. when clicking the icon, a nice popup will appear, populated with a list of all your bookmarks and their links, whenever you start typing search terms the list will shrink to contain only the relevant bookmarks.
This extension allows to instantly bookmark every page which interests you (no need to find which folder suites best, just bookmark it), while retrieving the page afterwards becomes a breeze - just search the keywords, and open it.
