OT: Zerohedge
It's what I would call "fringish" in that they seem to dump many interesting reports onto the site (commodities, sovereign bonds, state of the economy, etc...) but then they mix in silly gold / silver speculation and copious photoshopped Obama / Geithner / Bernanke pics alongside some over-the-top commentary.
The site was putatively set up by a Goldman employee that had acquired the company's flash trading algorithms. I started following it then because it was information heavy and littered with economic reports. But over the year or so it has migrated towards buffoonery, with many people using it as a platform for their various rants.
