Ben, I'm glad you went past 100,000. Now I can stop trying to be the first to get there and relax.
As for the playwright/screenwriter question... One of the big differences between a screenplay and a play is that in films/TV there are so many middle men/women between the writer and the finished product. A film can be made much better (or worse) than it is by the editor, the cinematographer and half a dozen - or more - others (I'm not including the director and actors because their input applies to stage, as well, of course). Whenever someone compliments me on something I've written, the first thing I always say (after "thank you") is "It all came together well." That's not being modest - it's the truth. When that happy convergence of the perfect group for a particular film happens, it's a rare and glorious thing. With the stage, it's more straightforward. It's the words, the director, the actors (of course the lighting, costumes, etc make a big difference - but they serve the play, not make the play.)
That's the beginning of my thoughts, I have some things to do now, but will continue later, or maybe one of the others will say all that is necessary, and I won't have to.
