-the game is still relatively new
-Fans don't have players to associate with. Most of the players are still unknowns, at least in comparison to BW stars like Bisu or Flash.
-Many viewers won't travel to the Gom studios, especially when the MSL and OSL are at the same time.
Cheese isn't even the issue. During the Nate MSL finals, Flash 8 rax'd Jaedong and Jaedong countered with a relatively quick spawning pool.
