The new proposed javascripted bookmarks display is available for the next few days at:
http://web.burca.name:8002/bookmarks/
I tested it with a few of the browsers I have access to and it works. I don't have access to any Mac browsers so I can't tell if it works on those, but it should.
I've uploaded some sample bookmarks I found on the web for test purposes. Select the "view public bookmarks of registered users" link to see them and then go to the "Javascript" tab.
If you create a test account and upload bookmarks, be aware that there's currently an open bug which makes it look like the bookmark import has failed. To get around it, just start over from the index page after importing the bookmarks.
