Why does it take several orders of magnitude too long to load? Makes me very concerned to implement it in any production application of my own.
Settled out with trying http://ant.design/ which has actually been pretty nice as well.
Seems most React components libs are material design and I can't stand the look.
It has a nicely designed DatePicker [1]. Semantic UI doesn't currently have an official implementation of a Date Picker (although there are unofficial versions on GitHub).
Ant is good at making the css importable module by module using webpack. Semantic ui could adopt this approach too.
Have you had mobile problems with Ant? Seems a touch buggy there

However, there is the bigger problem that bootstrap feels more and more like a sinking ship.
Semantic and Foundation are both on my list of things to look at.
Though it is for a private project. I'm not sure I will use it on a professional job due to the size of the css. I spend a lot of time importing things and I'm never sure how much weight and runtime complexity is being added.
