Database of Valueable Book Notes?

Just wanted to see if anyone would be interested in paying like $5 a month for a database of nonfiction book notes. The notes would be well thought out and provide actual value. The notes would be on ways to improve one's life through habit formation, ways to improve a business or other value that can be extracted from a book.

The cost of buying a book and reading can oftentimes be much greater than $5. Just curious if anyone would be willing to pay for something like this.

I know there are a lot of book summaries online either through simple googling or Blinkist but I feel as more value can still be extracted from all these wonderful books. Written notes covering more than just a basic summary would be the main idea. Please let me know if you'd be interested.

Not trying to self-promote, just curious :)
