Okay, trying again (as I don't want to do my own writing tonight it seems...)
1. Wrong starting place - Okay, people do sometimes start at the wrong place, although few places are the wrong place if you sell it with enough panache. And starting in the middle? Whut? Look, I think the best piece of advice I heard for starts came from a song:
"Something's happening here,
and what is ain't exactly clear"
Something should be happening, and there should be a question about it. You've got to go some as an author to sell a reader without that, and readers will probably read something into it. Is that starting in the Middle? Maybe, but I think that's a misleading way of putting it. Plenty of good books start pretty slow at the beginning of something. Short story-centric, then yes you've got less time, but I still feel there's some starts out there not doing what they describe. And as for:
"Readers should feel like they have been dumped in the middle of a car chase." - As an absolute, this is very wrong.
2. Telling instead of showing - This is a whole article in its own right, but every reader uses telling from time to time. It's inevitable. The trick is knowing what's important and should be shown, and what just needs to be told to keep the story going and should be told.
3. Dead dialogue - Obvious. "Most of the sentences you put between quotes should equal at least three sentences outside of them." They should have got to this sentence earlier as a lot of the rest is waffle. I'm not sure this rule is true, but it's at least a fun rule to play around with. Things that might be exceptions to that - humour, which often rests on repetition and the banal; interrogation scenes, which are back and forth heavy and where the slightest variations of speech and response can indicate a shift of power. I would add that for me at least, writing realistic dialogue and writing dialogue that gets to the point and is dramatically punchy aren't the same thing, and if you're similar, then their suggested rule could be pretty helpful - although its maybe a better editing rule than writing rule.
"Dialogue is inherently superior to prose. If you can replace three sentences of narrative with a single line of dialogue, you are morally obligated to do so." - As an absolute, this is very wrong.
4. Undead dialogue - They've got a point but finding examples of the mundane things being featured in fantastic stories is super, super easy. I prefer this take on it from Rossio - "#36. Every single line must either advance the plot, get a laugh, reveal a character trait, or do a combination of two -- or in the best case, all three -- at once." I've used it once on this forum today, but it doesn't get any less true.
5. Impersonal dialogue: - It's true there's a great chance to improve a story here, but there's a bunch of really big stories that blow right past this one. Realistically I think you can have every character speak the same and if you get the rest right, it won't kill the story. But then... that's true of everything so far.
6. Impersonal narrative - See above. And "Narrators that are characters in and of themselves should probably only be used if your target audience is people who can’t wait for their next colonoscopy." Uhm... yeah, this is wrong. If anything, the fact it's out of fashion (but still features in some big successes) arguably makes it a great place for writers to go. Plus isn't this just 1st PoV in general?
7. Point of view is like a box of condoms: - True enough, although I'm pretty sure the number of non-writer readers who care that much as long as its clear is small. I feel like I'll see the PoV slip a little in most books at some point or another.
8. Fairydancing the point of view: - My eyes are glazing over again... *skips to the bottom* Okay, yes, consistency good. Are they going to mention conciseness at any point?
10. Chronicling: - "If his choice between walking, driving or riding the bus isn’t critical to the story, why in the hell am I reading about it?" - Mostly true, but the less plot-driven and more character-driven a story is, the more the accretion of those small choices is critical to the story, even if none by themselves are. And even in the Dresden Files, which is plot-driven and actiony as hell, I know how Dresden gets from A to B a lot of the time.
11. Mistaking motion for movement - Mostly right.
... okay, I'm done again. Not least because when you come down to it, most of these things are just... not really problems. Because you can commit these problems, often a lot of them, and still be a famous author. Should you? Probably not. But it's not a big issue if you're getting the major things right.
And fiction with glaring issues that get major things right sells far, far more than fiction that doesn't really get anything wrong but doesn't get major things right.
