Unlike Ian I do have a Facebook account, so I took a look. But it really reminded me why I gave up with Facebook, it presents things in an unstructured way with no real means to search for what you are interested in. And the posts are too short to describe what it is they are really talking about. I am sure there is good stuff there, but I am not prepared to wade through everything to find it. Sorry I find sites like Ian's with in-depth analysis of a topic or series of topics much more useful.
