Why are the ads interspersed in the post columns on the front page?
The pioneering design of the Cortex which provides front-page space for top community posts, requires that ads forego their own column – otherwise those using screen resolutions of 800×600 (about a third of all internet users) would not be able to see the whole site without shifting the browser view to the left and right while reading an article. Thus, for the front page – and the front page only – the ads had to be accommodated within the content columns.
