Free for Webmasters: social bookmarking tool

Hi Everyone.  I have developed a new free tool to help webmasters get their pages social bookmarked easier.  It's great for any content-type site (forums like this one, Nikolas!), and I call it TheBookmarketer. It's a simple snippet of code to put into an include file or on a page you really want traffic and some extra, natural links to.
 
Here is the page with the code:

Here is my explanation of TheBookmarketer:

Here is my explanation of how websites can profit from social bookmarking:

So how would you compare your service with addthis.com?

Interesting.  I had visited them a couple months ago, but they have made some upgrades since.  Funny thing, they list GetAFreelancer as a partner, but I can't find the button on their site.  Same with CableOrganizer.

We still have more sites, and I have a list to add, probably next week.  And we have the top sites pulled out of the list for easy access.

We don't have RSS buttons, and I do not have plans to add it.

Those are the main differences.
