Edit: As a commenter suggested, I will elaborate a little:
I'm a big fan of minimalist and lightweight UIs, that's not my issue with SourceHut's design. My issue is the disregard for several established UI principles (balance, proportion, repetition, etc.). Some examples:
- The login[0] and register[1] pages have completely inconsistent layouts (left aligned vs centered aligned, one has a header and the other not, etc.).
- The margin between the top navigation and page content is inconsistent from page to page.
- Inconsistent styling of links. Some links have an underline that disappears on mouseover, while for some other links, it's the opposite[2].
- Inconsistent use of margin/padding all over the place.
Etc.
