No, I don't mean the rumors of impending presidential indictments (that would be an implosion), but the dramatic expansion of our companion blog, POTUS.

Rick Shenkman, HNN's editor and sometime blogger, has brought on an incredible bunch of presidential scholars:

Kathleen Dalton; Alonzo Hamby; Joan Hoff; Jeffrey Kimball; Stanley I. Kutler; Allan Lichtman; Timothy Naftali; Chester Pach; James Pfiffner; Rick Shenkman; Melvin Small; Gil Troy; Ted Widmer; Lawrence S. Wittner; Julian Zelizer

So, it's now a group blog from which we should expect a great deal. Some of these people have blogged before, or written for HNN, so they should know what to expect, and what we expect of them.
