I've just added a social bookmarking plugin to my blog called "Social Bookmarks" by Apostolos Dountsis. I think it's a really cool plugin, so I just thought I'd share in case someone else was looking for a good social bookmark plugin.
This one allows you to to have the links both at the end of each post on your blog and on the pages you make for your blog too, if you have those. It also gives you the option to select only to have it on certain pages and not on others.
Also, it gives you the option to hide or not hide the icons and lets you decide how fast the drop down speed loads and which sites you want to include or exclude... And a few other things.
Just thought it might be useful to anyone looking for this sort of plugin
