I think you're mistaking the 4e Rules forum for a 4e-inclusive forum. It's not. That might change in the future, but 4e Rules is for specifically that. The grind problem definitely is a more general issue to 4e design, and as such belongs in General.
In addition, too many threads on one topic is a problem that usually quickly resolves itself as most of the threads drop out of sight. That wasn't happening with the incredibly annoying edition war nonsense, so we closed them and banned the topic bwah ha ha ha ha!
Ahem. Sorry, got carried away.
