"Now, we’re well aware that a lot of people either don’t have time or simply don’t want to read a huge wall of text. So we will introduce a tl;dr pros & cons section at the bottom of our reviews, so you can quickly take away the key points from the review without necessarily reading the whole thing."
I know it's not my place to say this, as I don't run a website, but I really don't agree with this. I don't feel like a writer's hard work and effort should be cheapened just because someone is to lazy to, or doesn't have the time to, read the review. To me, it's just as bad as a review score. If someone can't be bothered to read a full review, then they don't deserve to know what it says. If they don't have the time, they can just read it later. That's the great thing about written reviews; they're there to stay.
I do think that taking out review scores is better than nothing, and it's a great first step towards a better environment of which to share opinions, but a big reason why I've personally stopped including tl;dr's in my threads is because people will often skim to the bottom of the post, only read the bullet points, and then respond with criticisms on my opinion that are already addressed in the full work.
People treat the tl;dr as if it's the full review and ignore the carefully crafted string of opinion and thought that precedes it. I just don't think that's fair to the writer.
