bookofjoe moving at flank speed sans compass?

I about sprayed my coffee all over this morning when I turned the page of today's Wall Street Journal and encountered the headline above.

This is supposed to be closely held information.

There is a leak here at bookofjoe World Headquarters and I aim to find and close it, thought I.

Then I read Yuka Hayashi's story (below).

Doh.
