Large saas, social media, and rich media delivery services have many times more complex factors than a simple content site. Why do you think Netflix, Facebook, many major banks and loan servicing institutions and most financial portals have chosen the web app strategy. It's not just because they are idiots and don't get it, it's that theyve recognized the unsupportable nature of multiple mobile platforms with such limited penetration.

Didn't suggest otherwise. But your reasoning is flawed, I'd imagine. Your suggesting that they don't go native because smaller platforms have limited penetration? If so, that seems silly. Why not support the platforms with large penetration natively, and support the platforms with smaller penetration with a web app?
I'm not suggesting going native for every platform, but going native for none because you can't do them all is even more silly.
Besides that still leaves you with Android and/or iOS plus web -- two to three times the development costs. This becomes very hard to justify for such a small percentage of total product users.
