I suspect that I know what my post was about probably better than you do, and my post was about the "what do you do?" framing that BookBarbarian talked about in his post.
No doubt you know your intent, but we only have your words to respond to and those words certainly included more than an observation of the four words "What do you do?" as already shown above. My response was to words other than "What do you do?" as was my factual claim about Dungeon World and D&D 5e having the same basic structure of conversation for the DM and players, a claim that in your view is "downplaying" the game differences in the games. My intent, which I no doubt know better than anyone else, is not to downplay the differences as you humbly asserted, of which there are many, but to show the similarities and how someone could have derived this approach from the four corners of the D&D 5e PHB.
Come on, this glibness is being disingenuous. You know that this isn't the point I was making. It's sidestepping using "what do you do?" as an intentional part of GM framing rather than just a conversational happenstance. I'm not sure why this is something you would want to downplay since this is something that BookBarbarian found laudable about what you did.
The only thing I'm attempting to downplay is any potential claim that PBtA games and D&D 5e are somehow different when it comes to this aspect of the game. While I'm happy my example play has benefited BookBarbarian's game, I can make no honest claim to that specific thing being attributable to myself or any specific game.
To bring this back around to the topic of how online games influence a DM's style, it occurs to me that "What do you do?" or words to that effect are a must in online play because of voice technology. It's like saying "Over" on a CB radio - you're telling others it's their turn to speak so that you're not interrupting each other. This is especially helpful if you're not using video.
