I don't really see how we get people into the game faster without having more available slots. I'd certainly love to hear ideas for that, and maybe those could be implemented along with an expansion so this doesn't happen again in a couple of months.

Though honestly, I'm not entirely convinced that it will. You seem to be assuming unlimited growth, but that won't necessarily be the case. A lot of the apps in the pool are seconds and thirds, not new players joining the game, and those people probably aren't going to rush to app again immediately. Things might find more equilibrium when more of the people already in the game have balanced their individual lineups.
