Alright, I went above and beyond on this review 😁:

• I have updated the https://www.notion.so/mui-org/Blog-247ec2bff5fa46e799ef06a693c94917#9c47cb10d26e4a95be23b01fdb96f431 to cover the need to add the intrinsic dimensions of the videos and added them to avoid layout shifts
• I have sorted the headers to always be 1. community 2. pro 3. premium
• I have fixed a few typos
• I have added more visuals
• I have flattened the heading structure to be easier to navigate
• I have removed all the links in the headers as I feel that it makes it harder to browse the content, and also, doesn't always clearly label what the link is about
• I have compressed images
• I have explained why we moved a feature from the Pro to the MIT plan.

I can't think of anything else that could be improved, I went after all the avenues I wasn't blind on. I love it!

Thanks for the great improvements, @oliviertassinari. I love it too!
It will be the baseline for the next blog posts.

Looks like great improvements to an already very well done piece! 🙌 Love the table of contents. We might even want to consider autogenerating these on the blog in the same way we do in the docs.
