I was thinking about the use of bookmarks stored in your browser by search engines. We all know that links to and from websites are very important for rankings. But what if a search engine such as Google had access to the stored bookmarks of your main browser. These bookmarks could be worth way more than a link on a website.

Anybody who uses bookmarks al lot will have them divided into groups by, for example, subject of the website (forums, music, clients, etc.). This factor could give the bookmark some relevancy.
Plus there is the simple fact that a website that has 1000 known bookmarks pointing to it will obviously be less popular than a website that has 1000000 bookmarks.
And these "links" are controlled by the actual visitors and not by the webmaster or optimizer.

All those links on the net these days are growing out of control and this might be a way to bring back some order. Allmost nobody has unused and unimportant bookmarks, am I correct?

I very intersted in your reactions on this topic.
