A commenter suggested I add Linkroll to the bookmarklet marklet maker collection, and that was an easy one to roll into the tool, which puts it up to a choice of 8 different web site submission tools that can be addressed with a click on a bookmark link.
Linkroll is another "social bookmarks" site, though instead of tags there are categories, 6 of one versus half a dozen donuts of another. It looks like it has some finer filters possible to put on links, and ways to collapse collections to RSS. Interesting, but I find having 3 primary sites to post links to is more than enough work. Furl is still my main dumping ground.
