I liked the part where they talked about the blocks with the blocks and the block blocks and how they all block together.

I thought the reference to field pioneers was a bit much, I wouldn’t have the blocks to do that with a straight face. I wish these app makers (see also Figma, AirTable) would refrain from making their self-aggrandizing “we’re bringing computing to the masses”; what a load of blocks. What you’re doing is creating a product (another silo in waiting) serving a market that presently is interested. This block model is also not unique (see WordPress and Drupal): Notion may be refining some of that in a more seamless experience, but this is a different kind of statement. Perhaps “we added collaboration to blocks” would be a possible claim for uniqueness.

Aside from this, I found the technical decisions interesting and worth a read.
