Chip,
You'd want the JFBCFan (not feed) module. The Fan module is meant to show the latest activity updates to your Facebook Page. The Feed module is meant to show activity by users on your site.. so if a visitor comes to your site, the Feed module would show which of their friends have Like'd or Commented on a URL of your site, etc.
I hope that helps explain, but if not, or you need more info, just let me know.
Thanks,
Alex
