That's what I say about most all commercial or "mainstream" sites.
Some of the best content on the internet is "ugly." And by that, I mean specifically this site: https://www.agner.org/
it's an interesting thought experiment to try and make sense of what it is about a website that makes it seem ugly, or not ugly. at what point does an 'ugly' web site become beautiful? is there a threshold?
i'd like to see an example of a site that you feel is not ugly, not so i can be a contrarian and say 'well, i think those are ugly!' but, just to get a feel for what you believe is exemplary of beauty.
