Like so many, I read the Prog in the order it arrives, invariably starting with the 'Damage Report' segment. Except on occasions when one particular story has some week-to-week thrills going on (that tends to be something written by Wagner or Abnett, who have that writing skill well-honed!), and I might jump straight to that. Reading out of order digitally is a bit of a pain - you have to take a bit of a stab at guessing which page from the list at the bottom of the screen will jump to the correct point. Trying to re-read each episode of a single thrill using my digital progs becomes a bit of a chore, which often doesn't do the story any favours. It's almost as if they want me to buy the collected editions.
Conversely, I get the Meg in original paper format, and typically read each thrill (and some of the articles) in random order, perhaps because I enjoy the ability to leaf through it in a way that I can't do digitally.
I'm also long overdue a Dredd re-read focussing on the Carroll-scripted efforts. I suspect he's been seeding certain plot elements for a lot longer than I've noticed.
