Who is Josh Shear?

This blog is linked from www.JoshShear.com, someone I have never met before. Of course, before I email Josh and ask him about it, I must submit a flurry of wild and possibly offensive suggestions. Maybe he's a bored astronaut in space looking for some on-line entertainment? Maybe he's really Tim Armstrong, and in some twisted reality, coming to stalk me? Maybe I've met him somewhere in life, but remembered his name as Josh Bear? Mr. Shear, if you're readings this, feel free to e-mail me, the worse that can happen is I write back (with caustic rhetoric!).
