You may now determine which module first appears to visitors of your profile page. Just go to your profile page and click the settings button in the black bar on the right (your name is on the left).
You'll see a "Customize" tab -- click that and then select which module you want visitors to see. It's now set to Audio by default, which is probably what most will want, but some may want focus to be on youtube videos and others may want their blog posts to show when entering their profile page.
It's your choice.
