Why? I'd argue most users of that site like the skeleton ASCII-style UI, which is also fast (at least when compared to the today's JS-riddled sites).

I am curious too as to what needs changed as well.

It appears functionality efficient, well organized, and fast as you observed.

You don't understand UX/UI at all. It's User Experience and User Interface. This service is just obsolete and unfriendly. It's not about ASCII style etc.

Why, what's wrong with the UI?

Not react enough.

I have not downvoted anything
