It is too bad the Facebook users have to make their profiles open to the public in order to work, but that is a Facebook privacy issue, I suppose. I don't have many users on my site because of this. There are many Facebook Connect type components that pull the status without having to make the profile open.
Anyway, the support is great with any questions I have had. I am surprised more people aren't using it. It pulls all your social media together and displays them in one place. I really love this product!
FC documentation is a bit on light side, but I have found the forum helpful. To be honest, it is pretty intuitive, so I haven't relied too extensively on the forums but there are a few regular that offer good advice.
All in all, this is a great component and should be standard in Joomla!
