Page with missing ‘articles’: Desktop Environments and Window Managers - Manjaro
Screen Shot:
This follows a pattern—see Deepin and GNOME below. After all, the main article is clickable right above the text.
The text seems to explain what can be found under the link above it.
It does indeed. I suppose the wording could be altered a bit to make that more obvious. 
As has already been noted, there is a link to the main Budgie page, though I agree that it looks rather empty without at least a brief description there.
Keep in mind that the page is only intended as a superficial list of Desktop Environments and Window Managers, with a few pictures.
At a future time, perhaps this will be expanded on to some degree, but in the meantime, detailed information about each environment is best found with an Internet Search.
