I used delicio.us back in the day before yahoo dumped it.  I moved to Google bookmarks.  Its a horrible interface, but it lets me store the bookmarks.  Finding them again is next to impossible.  Pocket I tried but the read it later feature would mess up articles that had code in them.<p>I had this idea at one point to make a system that auto organized the bookmark added by 2 or 3 concepts and you would choose the best one out of the suggested.  It would be like having your closet organize itself.
