I also just want to chime in and say that I absolutely HATE websites that feel like they're been over-designed.
perfect = hackernews
horrible = digg.com
I feel like the "uses webframework python $buzzword, javascript $buzzword $buzzword $buzzword" speaks to this. SOOO many websites have got too many distracting buttons and things to click on, and no actual <i>content</i>. Look at something like craigslist...its perfect. It's clean, and it gives you only the information that you want.
Look at hackernews...same thing, nothing but content...yes there is some of that web2.0 (i hate that term) sauce on it, but it is a compliment to the content, not the main attraction of the site.
Digg's design is not horrible. C'mon. They've won design awards with it and have millions of users. Hacker News has no design, which appeals to an audience that would love to think that code (a.k.a. content) is the only thing that matters in a business' success and that everything else is superfluous.
Digg's audience is more into fashion/style/cool stuff. So they should get some colors and a few gradients here and there.
I agree - digg has a fairly elegant design that's easy on the eye, without being obstructive. I don't think hacker news would suffer a great deal if a :little: more attention was paid to visual design. It doesn't really matter, I think people come here for the content, and that's fine.
Rater than comparing hn with digg, the comparison I saw somewhere was with http://www.newspond.com/ - an example of a site that looks nice (if you like gradients and glasy, round corners), at the expense of usability (only 3 posts per screen height etc). The first time I visited it, I was genuinely impressed by what they've archived, visually. But I've never been back since.
My personal taste is similar to yours, but I've learned the hard way that your visual design should be shaped specifically for the market you are targeting.
The biggest mistake you can make in visual design is to be guided by taste rather than understanding how different styles work psychologically and what is suitable to your target market. Some hackers deride "design" because they've either never worked with a talented designer, or they don't understand what design does. However there's quite a bit of science to design as well, it's just not as quantifiable as code.
This is a very weak description of what a hacker is by the way.
