I believe, as the author of this document does, that modern roleplaying lends itslef to being "stale" and "boring" more often than old school gaming.
I hate to tell you this, but this whole thread is just an inch shy of an edition war. Not only that, it comes across as pretty "one-true-wayist" and basically sounds like you played early editions with a good dm but have only had crappy dms in later editions.
Let's take the whole "I'm flanked and want to dodge out of the way so they hit each other" thing as an example. There's this page in the 4e DMG that is there so that pcs can do "stunts" rather than just relying on their powers. The tools are already there. A good dm will use them. And a crappy dm won't allow the pc to be creative, regardless of edition. Are you seriously positing that every old school dm would automatically do for the dodge-hit-each-other thing? Of course not. And would you seriously tell me that no new school dm would? You can't, because I just pointed to the new school page that says, "Here's how!"
The key to good, or at least one key, is a good dm. Period. A crappy dm runs a crappy game, even with a good system. A good dm runs a good game with even a poor system- and a great dm runs a great game even with a crappy system.
I definitely agree that there's a difference between old school style and new school style, but it isn't the stuff you're pointing at. To me, it's more an attitude. An old school style dm isn't afraid to destroy your gear, kill your character, remove your limbs, give you cursed items, and all without checking with the player first. An old school style dm uses your magic item wish list for scratch paper and then throws it away. An old school style dm is a referee and adjudicator. A new school style dm helps make sure that everyone is having a good time even if it means that he pulls his punches and limits his dirty tricks (Mordenkainen's disjunction, I'm staring you in the face). A new school style dm doesn't use many random encounters, because they throw the game off track. A new school style dm tries to ensure that the party is relatively balanced so nobody is useless, makes sure they have appropriate gear for their level and doesn't use encounters 19 levels above the party.
Each type has advantages and disadvantages, and some people prefer each. Nothing wrong with that, and with discussing it. But I think you're doing the new-school guys a disservice in the entire framing of the thread.
