Eluma is a bookmark manager with more on top. Choose to get alerted to any important items, as they happen - right to your desktop.

JigJak does what they all do - adds an icon to your browser, lets you add stuff, comment on pages other people have added (ala digg). Looks fine, but equally nothing particular to recommend it.
LinkBunch lets you put multiple links into one small link which you can share over IM, Twitter, email or even a mobile phone SMS.
