Sometimes, Giving It A Name DOES sort of "make something be".
Take podcasting. It's the year's big internet technology ... but it's been around for a very long time. Before that it was just audio on the internet, and some folks had a subscription model and some didn't. A few things came together and somebody called it "podcasting" and suddenly it was hot crap on a stick, and even big media needed podcasts to stay "with it".
Same with Blogging. Yeow. People had livejournals and the like for YEARS before "Blogging" became a big buzz word. Then everybody had to be a blogger and have a blog and blog from work.
"Let It Ride" is merely a facet of granularity. It's always been there. I've used Let It Ride before there was Let It Ride. Sneaky Pete rolls a Stealth check, the orc guards all Take 10, and we're done. But it's a matter of perspective. Some people may not see that in the D&D rules, though it's really there. You can even, gasp, not roll at all and have everybody take 10 and reduce the challenge to a story-board moment.
Just a second ... I have a new core mechanic. Everybody takes 10, UNLESS they spend an action point to force a roll. Players will only force a check when they either need more than 10 to suceed or will get additional benefits for a greater success. I'll have to think more on this.
