I guess at some point readers will only follow their preferred territories.
But as of now, why would posters spend time figuring out were does their post fit? Specially given that everyone is probably going to read it no matter where it's posted and weird/niche territories are more expensive.

If we want territories to thrive and make sense, there should be an incentive to use them correctly. At least until the “natural” incentive of user segregation is there, which only comes after territories being used properly.
