First, a reintroduction of sorts. Nearly every time I’ve gone back to look up a post from the Salon archive of my blog over the past few years, I felt more than a moment’s nostalgia. Writing a weekly column here has always been a privilege, but blogs have come to dominate the Internet for many good reasons that I learned back in the early days of the form. So when Joan Walsh asked me late last year if I would resume Joe Conason’s Journal, the answer was easy -- even though my life is more complicated now, with responsibilities at the Investigative Fund of the Nation Institute, a new book on Bill Clinton’s post-presidency under way, and my column for the New York Observer (plus twin toddlers at home).
