Delancey keeps track of your frequently used bookmarks.
It fetches your last 100 bookmarks from del.icio.us and presents them in an alternate interface.
Just enter your username and/or tag, there is also a link down the bottom called “permalink” which will change the page you are on to a permalink address.
The idea is also to make this a frequently used favourites page, that’s why you can make permalinks, and also also change the name of your bookmarks, and use the Delancey bookmarklet so sites are automatically tagged “Delancey”.
When you click on a bookmark, while it launches the page it also records the click on the Delancy server, and annotates the bookmark with the number of clicks.
What about if it collated your top clicked bookmarks across all tags onto a page (ranking your bookmarks according to your clicks)
