1. Tiny text. If your audience can't read it - don't include it. This seems to be everywhere. My most hated phrase in a talk is "you can't see this but". See here: https://imgur.com/a/1B8j6 I can barely read this close up on a high quality screen. Are your audience really going to be able to read https://imgur.com/a/2YtMF on a projector?
I always feel if I'm at a talk and someone shows me something I'm not supposed to be able to see that they don't care enough about the talk.
2. Colourblindness.
There's a colouring on clustering: https://imgur.com/a/d0P6T
And here it is if you're red/green colourblind: https://imgur.com/a/1g8vc
An easy way to work with this is see if your slides work when black and white.
3. Tables https://imgur.com/a/KLNtQ
Are you really trying to get across 40 pieces of information? If not, why have so much stuff here? Even if so, please don't centre all your columns!
Then shows a table of numbers that are not aligned to the right with the same number of digits.

Column alignment is pretty subjective (and again, I think the chosen one looks more pleasant than what you're proposing), what the writer was getting at was making sure that the point you'd like to get across is being highlighted in someway, hence the red column amongst the black.
No, there's absolutely nothing subjective about this topic. It's objectively easier to compare numbers and see differences when they all have the same number of digits AND are aligned to the right.

But there's lots of good advice here, it's not really fair to question the validity of the entire article just because it left out one minor thing that you care about.
Many of the same discussions and others contain helpful advice for presentation content as well: Ask HN: How do I learn to use Powerpoint well? https://news.ycombinator.com/item?id=13078654
