If you think that Mr. Rensch and Miss Shahade are good, you should watch Maurice Ashley and Yasser Seirawan during the U.S. Championship and GM Judit Polgár during the World Chess Championship. The latter is perhaps the best.
That said, I think active learning is still the best, but since the younger generation seems to have their noises interminably in their iPhones and Androids you may be correct.
As far as these side comments, it argues for a pay-only site in my opinion. Then only the serious would be here.
Holy Moly, if there's anything that's going to kill chess books, it's the following:
Watching Live Commentating of a Chess Game in Progress. In my specific example, my Eureka moment was clicking on Chess.com this morning and watching IM Danny Rensch and WGM Jennifer Shahade commentating on the Sergey Karjakin - Georg Meier Speed Chess Match.
I'm listening to these masters explain things, and I'm like, oh my gosh! The level of thinking and analysis is so helpful! Seriously, if you never crack open a chess book, and instead, just do online chess and watch videos and live chess commentating, and if you're young and bright enough, I don't see how you can't become at least 1800 or higher in a fairly aggressive timeframe.
Active Learning of course, is better. But the next best thing? It's gotta be watching videos of masters commentating on other master's games, and making it fun.
The only thing I would want is to get rid of the live chat box that's next to the screens. The peanut gallery is SOOOOOO distracting. I keep glancing over to watch comments. And it just gets ridiculous. "Hi Naka!" "Danny Rensch has got a Stench!" "Can we have Anna instead of ....?"
I mean, c'mon. I'm looking around for an "x" to close off that chat box, but there is none.
But seriously, if you don't have time for active learning, watching masters live commentate GM games in progress is really helpful.
