Currently, using the PingThis module, will allow you to add a link to your posts that will give yourself along with visitors to your site the ability to quickly share posts by using Ping.fm. There couldn't be a better way to allow users to promote your page(s) than by simply posting it to ALL of their social networking sites at once!!

UPDATE: This module has an official release thread here at himerus.com. Further comments should be submitted there.
