I have been using Google Booksync for some time now.
In the beginning, everything was good, and the bookmarks sync perfectly.
Now, all my bookmarks are messed up.
Solution?
http://sitebar.org/
I have installed as a subdomain on one of my websites.
It uses mysql and php, to control your bookmarks.
This enabled you to access your bookmarks everythere.
