We've made a few small changes to the site today, including putting more stories on the front page for you to read. Welcome to the modern age!
There's also a new way to interact with stories in our right sidebar: You can now set the sidebar to a one- or two-paned interface (here's a helpful video from Lifehacker explaining how it works - the same controls are available on io9).
The one-pane interface locks the right sidebar in place so that when you scroll the page, it scrolls along with the page. The two-pane interface (available on Firefox 4, Chrome, and Safari) works just like the previous default: You can scroll the page content and the sidebar content independently, using your mouse's scroll wheel, your laptop's trackpad, or by clicking and dragging the scrollbar itself.
Finally, you can still toggle between "blog" view and "top stories" view by clicking the button you see pictured at left.
