When Google killed Google Reader, the bloggosphere took a severe hit and the content quality went down because there weren't enough readers to justify the effort it takes to maintain a high quality blog.

What's left is a decaying wasteland of blogs, most abandoned, a lot are now SEO spam, and 99% are not worth reading. BoredReading is a way to read the remaining great blogs that survived the ice age.

To add your favorite blog, please suggest it here! I get emails every day which helps me maintain a high quality selection of blogs!
