Nu52 and NOW may not work as well as publishers hope, and may not be what you'd do, but it's nonsense to say publishers do nothing.
Changing content - your good old days, Blade's all ages, whatever - is a gamble when no one is producing books that sell significantly better in those formats.
More to the point, your reluctance to piss off your current customer base by offering free/cheap comics to new readers is the exact same argument. A reluctance to risk what you have for what you want...
I'd love to see more varied content. I don't think one sweeping change to one new model is an answer. (Though I do think Now writers like Aaron and Bunn may be moving closer to what you and Blade advocate... With a codicil that I'll probably drop their books if they do)
Digital - I prefer paper, and love the LCS experience deeply. After 35 years, why wouldn't I?
But I won't willfully close my eyes to a better business model that encourages/enables everything you and I agree the industry needs. Even though it does so at the cost of massive change to the way the LCS fits into the system.
I think our core disagreement here is that you're what - in my industry - is called a 'safe hands' manager. You know your job and you can keep the ship on course, but you're inherently conservative. Thing is, when the ship is sinking, you need a 'turn around' manager. One who will think outside the box, see opportunities and make bold/risky decisions and see them through. Someone who is not afraid to speculate in order to accumulate.
