A lot.
To be successful in the web novel style, my opinion is with Sailus here. Traditional writing rules are more like... guidelines, as Barbossa would say.
Okay, let's make sure we all are clear on something here, because I think we all agree, but thoughts are flying all over the place.
There is a difference between being a good storyteller, and being a good writer. Rowling and Stephen King, are, according to other writers, not good 'writers.'
Rowling abuses adverbs, and I don't remember the critisisms of king because of how dry and technical they were. So, obviously, there is flexibility when implementing.
As for the traditional rules, they are there to maximize profit potential and understanding. That's all it is. They aid your odds. If you're publishing, you follow those rules to increase your odds. It's always about probability.
Now, here is where I take minor issue. I want to ensure we appreciate the methodology here.
If you go right now, and you look at Shirtaloon's most recent chapter of He Who Fights Monsters, and you look at that chapter of dialogue, do you know which tags you're going to see, one after the other?
There are 50 lines of dialogue. There are 31 that have 'said' as a tag. 5 have asked. 5 have told. There are minimal exotic tags.
Also, I apologize. I can see how linking a video by an established author could be an argument of authority. There is no "right" way as you said.
I don't think you should apologize RepresentingEnvy . Appealing to authority is bad when you're doing it blindly. This guy probably has results. You're citing someone with experience in publishing. And to follow up on Sailus's thought, there is absolutely a wrong way to write in the context of having other people read your work. Anyone that says otherwise hasn't experienced it.
The wrong way to write, is when you write and no one understands what you're trying to convey.
How could anyone call an incomprehensible mess, "right."
Writing is about communicating ideas. If you don't communicate you're failing.
And then we go back to the guidelines. The whole thing with 'said' and them is born out of making communication efficient, because efficient communication is more likely to be profitable.
