I did a similar analysis a year ago and came to the conclusion that ProseMirror (https://prosemirror.net) was the right choice for my project. ProseMirror is an excellent toolkit for building your own rich text components and happens to also be written by the author of CodeMirror. It does not give you as quick an out of the box experience as slate (or any of the other rich text libraries out there) but its speed and flexibility is excellent.
I am really curious about this point of view. Many of my friends and colleagues share it. Do you really see no issue with downloading something for free if it isn't provided to you in a way you can pay for and consume that you prefer? Are you okay that you are not paying for something that really does take a large amount of money to create?
There is a version of vimium for firefox too. I prefer using it so i don't have to think about the minor differences between vimperator and vimium when I switch browsers.
Cool site! I would suggest trying to scrape taphunter.com to find beers to add to your system. Doing that weekly for some of the bigger beer towns in the country would add a bunch of brews to your list.
