Eh.
They seem pretty arbitrary and indistinct: a single campaign, even a single session, could combine much of what is there. They are far from all encompassing. And, like so many of these posts, mischaracterize the "old days".
Indeed, they are not exclusive categories. Many games and styles did overlap. This is merely an effort to codify the most commonly seen tendencies. And again, these styles are also reflected somewhat in the actual products put out by TSR and later by WotC. You can clearly see the Paladins and Princess style dominating a lot of 2e era TSR products.
Anyway, several gamers who did play in the "old days" gave the original thread their blessing already as being fairly apt descriptions of the most common playstyles back in the day. Granted everyone's own personal experiences are unique. I started with AD&D back in the day myself, and our game was very Knaves and Kobolds. When 2e came out, we played a lot of Paladins and Princesses, and continued playing that through 3e with a touch of Spellcasters and Simulation before moving on to Warriors and Warlocks in 4e.
