I don't know if this is a plugin or a theme problem, so I'm going to try and get support on both places so we can get to a solution for everyone.
Using Elegant Theme TheProfessional (http://www.elegantthemes.com/gallery/theprofessional/) + ShareThis plugin I get the share buttons on the posts listings and featured slider:

Using Shareaholic (http://wordpress.org/extend/plugins/sexybookmarks/) I only get the share buttons on the bottom of the full post (as it should).
I really would like to use ShareThis as I think is the best share plugin around.
