Link Roundup

I've not done this in a while. Here are some useful links I've found this morning:

1. A interesting Social Security overview from Jane Galt.
2. Why Peter Jackson really used New Zealand for the LOTR from Prof. Bainbridge
3. Some thoughts on the right/left divide by deacon at Powerline
4. Reflections on the "what I believe but can't be proved" from Joe Carter and David Mobley.

If this is something you want me to do more often (aggregating), leave a comment, and I will probably do it. Otherwise I'll continue as a mostly essay poster.
