Rather than answer this outright (as I don't have a complete answer), I'd encourage you to imagine what some of the things that would make a high impact journal, one that you'd find useful. Even if you don't have all of the answers, that would move the ball forward a bit, and put some skin in the game/conversation, as it were. What would make the journal high impact? Would there be costs associated with that? If so, how would you fund it?
