For some reason I really really love the web design of this entire site. It makes me smile.
It's not exactly retro, but it has a happy carefree hacker feel to it. And it's positive and not ironic or cynical in tone. Perhaps it's because the logos haven't been touched by your typical SV design bod!
Websites that hackers enjoy looking at often use bright colors overall + blue + stricter hierarchy than most (e.g. lots of boxes and a firm plan for nesting information). You might also enjoy: http://www.fieggen.com/shoelace/
Blue has been discussed to death, and bright colors are never ideal to everybody, but the sense of hierarchy is the standout requirement to me. Hackers can't get enough of it. I'd guess this is because of the typical ST personality type (Meyers-Briggs).

Also, Browserling is very nice.
