Social Bookmarking Widget Customization and modifications (addthis.com)
addthis.com has an amazing social bookmarking widget that integrates every possible social bookmarking site such as digg, stumbleupon, browser bookmarks, reddit, and sooo many more. While they offer some documentation on their widget there are additional features which you can tweak with the widget besides what is mentioned. Basically they are settings within the javascript file.
social bookmarking widget addthis.com specify url
By default the widget uses the current browser url, but if you are on the the main page of your blog and want the widget to specify the actual article the widget is next to you can specify the variable ‘addthis_url’ just like you do the other variables.
specify default title
‘addthis_title’ – Swaps out what’s in the title tag with a title that you specify.
specify caption share
addthis_caption_share – specify a different title besides the default “Bookmark and Share” on the dropdown.
specify custom css file
addthis_css – takes a reference to a css file.
put your brand on the addthis widget
addthis_brand = “Megatech”;
only enable certain sites
addthis_options = ‘facebook, email, twitter, more’;
position/move the addthis flyout menu
addthis_offset_top = 100;
addthis_offset_left = 30;
add a delay to the addthis flyout bookmark
addthis_hover_delay = 200;
Another site that does the same thing just a slightly different look is ShareThis

Hey there, this is a month old and since they’ve introduced some better documentation.
I just installed addthis at primitivemachine.net and thus far I’ve yet to use the RSS feature? Have you had success delegating your rss feed to them?
