Lee Olden came up with 2 social media optimization tools to make it easier  to share and promote of your content.

"The first tool is one we’ve received excellent comments on and it’s called the Social Bookmark Creator. In order to make it easy for readers to save a blog post or a web page for reading later or to aggregate resources using a social bookmark service, we’ve created a tool that allows you to add a social bookmark menu after each post or on a static web page.

What’s different about this tool from other social bookmarking tools and our own previous version is that the social bookmark links are presented in a drop down menu to save screen space."

I have not tried this tool yet - looks interesting! 

The next tool is a RSS Button Maker

"The second tool is the RSS Button Maker. You can see the result of this tool by putting your cursor over the orange RSS icon at the upper right of your screen on this blog. A list of the top RSS readers folds out so you can subscribe using your favorite reader.

Both of these tools help conserve screen real estate and also help to socialize blogs."

I would consider both tools to be "enablers" of social bookmarking, social media optimization and worth trying as often little things can drive more qualified traffic to your site.
