Good
http://howardlyon.com/blog/home/ - A blog with great content and a website that compliments the quality of the content.
http://www.lovelaneny.com/index.php - This is a well designed website for fancy pants high end real estate in New York, in fact it's so high end that when I got curious and decided to look the cost of some of these places, I'm pretty sure my eyes started to bleed.
Personally I think the whole theme is a little sappy but the smooth animations, crisp photos and good layouts work well. I'm pretty sure it works for their perceived target market too.
http://www.threadless.com/ - Modern, simple design is featured here with copious amounts of hipster tattoos, pop culture references and those god awful glasses that everyone seems to wear these days.
Bad
Note: a lot of these blogs have brilliant content, but really poor web design.
http://anthonyvanarsdale.blogspot.co.nz/ - the problem here isn't so much bad web design as it is a lack of design. It seems like the artist doesn't really care about the layout and design behind his blog. That's not necessarily a bad thing, at the end of the day it's about his art and that's all that matters. But I'm sure a bit of effort put into the design of the blog will compliment his artwork a lot better.
