Yes, right at the front page you can use your facebook account to post..
I didn't know that this site was linked to facebook.
Not anymore. I completely removed the linking between Facebook and CC accounts on privacy grounds; same goes with Google analytics.
The FB comments plugin only remains on a few pages now.
That is only because some people don't know how to set up the security on their facebook page
Why did you remove analytics?
Facebook connect shows on this page, i have it blocked through ghostery. Congrats are due though for the lack of tracking cookies on CC. Some sites i have visited have more than 20 including some of the most notorious privacy invaders like doubleclick.
