Aside from what has already been said (SemUI is a MASSIVE piece of CSS), Semantic UI is also not semantic.
<article> is semantic
<div class="article full width"> is not semantic, it's describing how it should appear.
You can break half of the examples page by just clicking everywhere and typing and such. I currently have three buttons stuck in the middle of their two positions, textboxes being broken, etc. It needs work.
Also it's rarely a good thing if your goddamn landing page makes an i3 stutter when rendering it. Doesn't really scream lightweight or efficient (although the biggest culprit is that background header video)
