If he didn't, I'll say it.

I posted a while back a list of all the elements of 4E that do seem to hearken back to prior editions, from the "short rest between combats" to the staying power of monsters, to the XP awards, etc. etc. There are a lot of elements that seem to imply "this worked better than what we have now" sort of changes. This really isn't the thread for in-depth discussion of it, though, as it's more about 1E.
What 1E resurgence has done however, even if a small resurgence, is make people mindful of the elements that make a game popular to average Joes and Janes, people who don't want to think about the mechanics very much, but who just want to either kill things and take stuff, or roleplay a character, or socialize with friends, or some combo of the three.
Games like Labyrinth Lord or Castles and Crusades do remind me that there was a reason (besides a Satanism scare) that people turned out in tens and twenties at game tables throughout the Seventies and early Eighties, and looking back to the old while thinking about the new is a good way to remind us just what was popular about those games to those people who weren't smitten with die-hard gaming, but just those who wanted a fun experience at the table.
