So here's the NEW LOOK!
In addition to the more modern, more dynamic feel of it, I think it's more user-friendly, providing easier access to posts, links, features, etc. It should allow you to better navigate and find the things you really want, as well as hopefully share it if you like it.
And on top of all that, it's fully compatible with mobile platforms too, so you can finally have a much better experience on your phones and tablets.
Please let me know what you think of the new design. I'm excited about it, so I hope you feel the same. But certainly let me know if you run into any problems.
