This got me thinking (and I wonder if anyone has some data/experiences/guesses about this): How many people put <!doctype html> at the top of their HTML files in order to opt-in to standards mode. I sure do! Every time I write an HTML file it's the first thing I write. I wonder if that experience is the more common one?
I admit to not writing "use strict"; in most of my JS files due to laziness (I prefer to use strict when I'm taking my time). I guess the carrot isn't as big in ES5 as it is in HTML/DOM, at least in my eyes. It seems like a pretty parallel situation to me.
But with a bigger carrot, I sure wouldn't be too lazy! And my assumption is others would gain the energy as well (unless there are still a bunch of devs out there not putting a doctype in their HTML, in which case the fear of Law of Least Effort is quite valid).
Does anyone have some data to quench my curiosity?
