While this may be helpful for business people and politicians, I think this isn't great advice for this demographic. A huge skill lacking within this industry (and of course I'm generalizing) is that of verbal communication. Wouldn't talking more, much like writing more, help that skill?

No, not at all.

Silence, like body language, is an essential part of "verbal communication skills" - that's the point I'm making. You can no more learn "verbal communication" without learning to use silence than you can learn "driving skills" without learning to look in the rear-view mirror... (poor analogy, but you get the idea)

Wouldn't talking more, much like writing more, help that skill?

Yes and no.

I think "talking more", in the sense of finding more occasions to speak: more meetings, more conferences, etc, would be helpful.

However, I don't think using more words during each of those occasions would improve your verbal communication skills.

Talking more doesn't necessarily mean you're saying more.

To use another popular adage that drives the point home: brevity is the soul of wit.
