Was finally able to get a nice vertical stack of these social media icons using the following CSS:
Stacked on the left side (See example at https://blog.webnme2.com)
Buzz
clear: left; float: left; margin-left:-80px; margin-right: 10px; margin-top: 0px;
TweetMeme
bottom:-65px; float:left; left:-75px; margin-bottom:65px; margin-right:-62px; position:relative;
Facebook
bottom:-135px; float:left; left:-80px; width: 60px; margin-bottom:135px; margin-right:-62px; position:relative;
Stacked on the right side (See example at https://blog.happyflier.com – site I help with)
Buzz
float: right; right: -10px; margin-right: 10px; margin-top: 5px; bottom: 0px; margin-bottom: 0px; postion: relative;
TweetMeme
bottom:-70px; float: right; right: -10px; margin-bottom:70px; margin-right: -55px; margin-top: 10; position:relative;
Facebook
bottom:-135px; float: right; right: -10px; margin-bottom:135px; margin-right: -50px; position:relative;
For the first example, I also had to change the template and style.css file to get the extra white space on the right side.
If you are doing a banner ad at the top with your template, you may also want to check it in compatibility mode in IE8. Both the banner and the social media icons did strange things when in IE8 compatibility mode until the wrapper was perfected to include the bottom and bottom-margin values.
