SquareSpace rolled out some new features, one of which you will find in the right sidebar. SquareSpace now stores Twitter posts on its own servers to speed load times. The widget is also interactive, allowing you to navigate back through older Twitter posts.
While I was at it, I slightly expanded the width of the content area and then increased the font size for posts to improve readability. If these sorts of things matter to you, feel free to leave a comment.
