You can see this straight from sharethis.com. You don't have to specify a site but you do need to log in.
HTML Code:
<script type="text/javascript">var switchTo5x=true;</script>
<script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script>
<script type="text/javascript">stLight.options({publisher: "b4f4f721-de8b-4e2f-8c74-d5175ea04b23", doNotHash: false, doNotCopy: false, hashAddressBar: false});</script>
Publisher value was "redacted" in earlier code post.
Sharethis wants the code in the <head> actually. (I'll take advice on how to do that as well...) I have another module (MailChimp) that also needs {'s, not in the <head>.
Things that haven't worked so far (assume the complementary closing tag):
{literal} around script line
