I just ran across the TSA's blog. They've been up and running a couple of weeks. The TSA. You know, that arcane organization that has illogical rules, terrible service, and unmotivated (and underappreciated!) employees? Yes, they have a blog, and apparently they listen to public input.
People expect a public face of you now. Really, they do. If you don't, something is amiss. You're hiding something.
