What happened to the GISDirtbag?

He (or she?) seems to have disappeared off the face of the blogosphere. After stirring the pot with several posts (see example), he is gone.

I wonder, did the lawyers from some unnamed giant take him down? Or did he say the wrong thing about the wrong person/group/software/topic and disappear on a lonely road late at night?

Perhaps he retired and I missed the announcement. In any event it all seems mysterious and to my suspicious mind, perhaps even sinister...
