Steven Den Beste that is. I used to read his old blog with regularity, and it provided some of the best in depth thought and history for the context around world events. He seems to be posting over at RedState for the time being.
He made a note about “please show some couth and don’t gush all over the comments. And how about not sending me email ‘welcoming me back.’” Just in case there was any doubt it was really him.
