Eliminating a line of space between Sociable and Comments

This is kind of an odd concern, and it may very well not have a solution. I’m playing around on a test copy of my blog looking for ways to improve it, and I’ve decided to add an extra line at the bottom of each post to encourage people to comment. However, there is a fairly significant gap between my Sociable plugin and the comment line. Does anyone know how on earth I can eliminate that gap?
