Sadly lots of planned featured needed to remove from FirmaSite theme because of theme rules in WordPress.Org theme system:
http://codex.wordpress.org/Theme_Review
I really was disappointed when i learn that most of stuff needed to remove but now i can understand their logic. While i dont agree those rules, i respect them.
All social integration (Facebook like,comments etc) is removed from theme because of WordPress.Org rules. They decide that some planned features are plugin territory. So i built a plugin for theme:
http://theme.firmasite.com/plugin/ or
http://wordpress.org/plugins/firmasite-theme-enhancer/
This plugin will add all those social integration soon. Sorry for misinformation on theme site.
