What would be representation of some real work scenarios? I think their test suite covers wide spectrum of operations enough so to be able to draw conclusions from them.
I don't get how people can use notion for personal info or basically anything else if you are not forced to use it at work.
Not even considering that your most personal information (journal, health log etc.) you don't share anywhere else twitter, facebook is stored in plaintext somewhere and can be used however they want according to their privacy policy which some nothing-to-hide folks might ok with but that everything you have written can go poof any second is nuts IMHO.
When I saw this mentioned on HN I immediately knew this kind of comment would be there because something along the lines and I am paraphrasing "its probably fast because its not enterprise enough" was repeated in every place the refterm was shared by different people even multiple times even after showing all the proof in the world that its in fact the opposite they almost refused to believe that software can be that much better than its standard today even to the point of bringing up arguments like 16fps terminal is better than 7500 one because so many fps would probably consume to much resources.
Before I found Casey's tone criticizing bad software off putting but now I understand that after many years of such arguments it takes toll on you.
I could write a long list of things you should probably do but if I could recommend just one thing it would be to watch this video https://www.youtube.com/watch?v=xsKYAa1ZXpQ it really helped me to understand how react works.
