Writing a web app is doing. Writing a blog post about writing a web app is talking.
I don't know J.D and I don't know the blog. If he makes money off of talking about doing, good for him.

This may be true for programmers (whose most productive work is generally unrelated to writing), but is untrue for writers.
You could phrase it as "productive talkers", whose talking is important, versus "unproductive talkers", whose talking is just hot air, but that starts to get close to being a tautology: the bad kind of talking is bad.
