Welcome to my Sphere of Inference. I reserve the right to infer anything and post it here.
To be frank, the name Sphere of Ignorance probably works just as well. And, while I didn’t take forever thinking about this, some other choices considered were: Sphere of Exfluence, Sphere of Effluents, Sphere of Impudence, or Sphere of Imprudence.
Of course, depending on the post content, any one of these titles may yet prove to be appropriate.
