Probably on my blog by selecting "Bitcoin" category from the drop down.

I've been writing more about the police state than I have about Bitcoins recently.

Most of my police state articles aren't quite so... academic in nature as my Bitcoin articles.

I have a low tolerance for tyranny.

Does anyone know how to input this character using the "Compose" key (unix-like systems)?

alt + 579

The alt-579 works on Windows.  It doesn't work direction in the forum editor; I'm not sure why.  It works in other editors, Word, wordpad, notepad, and even the browser URL.  If I'm using it in a post, I just jump up to the URL line, type in alt-579, and then cut and paste.  That works in Chrome at least, not sure about other browsers.

Yes, hold down alt, type 579, let go, and the symbol should appear. I just realized it works for me in Windows Wordpad, but not Notepad.  Try it in those.

I guess it depends on what Windows version you are using.
I'm using Win 7. Here it doesn't work in Notepad, but it's working in Wordpad and the Chrome address bar.
But only if the font has the symbol in it. In Verdana for example it's missing.
