First, when I load http://differential.io/blog and click a link for an old article, the content of the "Why Meteor will kill Ruby on Rails" article is displayed instead of the content of the article I wanted to read. This happens for every article.
Second, when I load http://differential.io/blog, scroll down to an old article, click the article's link, and then click my Back button, I'm directed to the top of http://differential.io/blog, not to the middle of the page where I left off. Very annoying.
