Murl.comMurl.com is a place which stores your bookmarks. This sounds like a stupid idea, but for those of us who use the web from multiple locations, bookmark synchronization becomes so painful you look for other solutions.
Murl gives you your own private space for bookmarks (although all the rules about not including private information apply here, since we don't know anything about the nice people running it!) where you can access your bookmarks from wherever you are. They provide a javascript thingie you bookmark, which when clicked adds the current page you are viewing to your bookmark list.
I've been using it for a couple of months now without any problems whatsoever.
