Many many words I've read trying to convince me why I shouldn't be having a good time using it, yet here I am more productive than ever thanks to it. Less experienced devs are by default funnelled into writing code that's easy to understand, only looking at one file, as opposed to people trying to do cute tricks where styles could be coming from anywhere in the project. It's SO much easier when the styles are on the component I'm looking at and I don't have to cross-reference between files. Plus people sticking to increments of 0.25rem instead of everyone using their own preferred units is huge.
When you work at a big company you can't expect everyone will write nice CSS. But Tailwind plays a huge part in making sure everyone writes something that's much more easier for the next person who has to read it.
