We live in an exciting time. Maybe it's the ease of internet access or the volatile political atmosphere, but there is no shortage of conversation and debate, and blogs are a great way to find people with whom to toss around ideas.
Here are a few blogs I really like.
The posts are brief, witty, and to the point. Very enjoyable to read.
This is a new one. Very thorough and informative. I don't agree with many Libertarian positions, but I find them to be critical thinkers and always worth debating.
This is a big blog with lots of topics and lots of people. It's also libertarian, but there are a lot of points of view there.
