DC's weekly comic 52 is one of my current favorite comics. Along with that official site linked in the previous sentence, fan commentary threads have been a mainstay on comics forums across the internet, and Wizard Magazine maintains a weekly commentary column.

Now you can add two 52-specific blogs to the list: 52 Pickup, and (much less serious) The Diary of Ralph Dibny.

UPDATE: Wizard also has a great weekly 52 blog by cover artist J.G. Jones.
