Galt's Gulch Online
I stumbled on to this Galt's Gulch Online site via Facebook. I've added it to my blog so I can check it out and see if it's somewhere I want to hang out. The Libertarian Party Facebook pages drive me nuts, but this doesn't look too bad from what I've seen.
For those that don't know, Galt's Gulch was the place where all the wise and rich men hid out when society collapsed after Altas Shrugged. An old Ayn Rand thing you'll mostly hear about from libertarians, and in negative terms from the progressives, of course.
