I run the blog A Susurrus In Carcosa where I write material of interest primarily for the 4e, OSR, and Savage Worlds crowds. I am one of the Stewards of the Assembly. You'll occasionally see my work appear on the GA blogs page as well.
My personal twitter is squeezebottle, and I also have a blog-exclusive twitter if you'd just like to hear if I've made an update either on GA or Blogspot. That one is susurruscarcosa. My email is firstname.lastname@example.org
