Are there any free social site submitter softwares I can download?

What I am trying to do is use a free software to send my url links to social sites like Digg, reddit, stumble upon, shetoldme, diig, buzz, blogger etc... Since I write article I thought if I do not have to do this maunally it would would save me time. I have tried the following but they do not have them all and there is no way to add more: Social Bookmarks Manager, Fast Directory Submitter, Choas, Able, Free Url Submitter! Thanks and have a great day! Sincerely Unique
