Does anyone else find Medium's website extremely slow?

Yes. It's so much better if you disable their JS completely, you can do that with umatrix.

I don't know if slow. But if you are using it to build a portfolio and show your knowledge, it's the wrong platform. Whenever I'm looking for some technical article and I end up in medium, I just hit back.

Super fucking slow and bloated, but its okay every once in a while some good content makes up for it.
