I installed Digg Digg a couple of days ago, and now our Facebook comments are not showing up.
Our site: http://www.sexyinspiredwealthywomen.com
I use this plugin for the FB Comments: http://pleer.co.uk/wordpress/plugins/facebook-comments/
I would also like to show the bar on the home page, either floating or normal. I have had to keep the Share This plugin activated since it is the only one that shows up on the homepage.
