I start typing the name of a site that I like into the browser bar -- and it fills in the rest.<p>It does this so consistently that it's very rare I even need to refer back to saved bookmarks.
diigo.<p>You can basically use it forever free. Payed version is for stuff that is beyond bookmarking, like big amount of annotations, HTML/PDF cache, teams etc.<p>There are versions for all browsers and mobile phones.<p>You can export everything, so no lock in. You organize stuff via tags. You can mass edit tags.<p>Its really good, dont look for anything else.
