From his blog:

F13.net engaged Raph Koster (again!) in a discussion about MMORPG economics, under the flawed assumption that any of them had one. Scott Jennings of Mythic Entertainment said so, and when he says ‘so’, it is. Hey F13 – stop baiting Koster, he has games to make.

Lum knows exactly what to write and how to write. And be effective. The content of what he says is nothing miraculous but he’s able to express what was already “latent” in everyone else.
