I think http://incredibletypes.com/ is a great example of a nicely done design blog. This page is very simple and clean. I love that you can see the columns on the webpage, at first I thought that it could be a programming error, but I like that from a designers perspective, you know exactly what the columns were used for.

This blog is a curation of many different graphic designers and I like that it’s in black and white when you first open the page. When you scroll over an image, it turns to color and includes the title and page that the design originates from. This makes the design stand out against the rest without clicking to a new page.
