I wasn’t trying to say either of those things. What I meant was:
Job posts appeal to a specific audience (people looking for jobs)
Posts by potential grantees appeal to a specific audience (people looking to make grant-sized donations)
I believe that the first audience is larger than the second audience, which means that presenting the former type of post on the frontpage is somewhat more reasonable. However, it’s possible that neither type of post should ever be frontpage/that we should amend our categorization system in various other ways.
