The new page was a mock-up, merely a revision in the process as they work on updating the look. It was not a final look, nor was it really even meant for the public, merely put up in the [Unknown LJ tag] community for feedback on how to improve it further. And, having gotten that feedback (more than they needed, from all the rabid, frothing-at-the-mouth screamers around this place...I actually came across someone making a petition against LJ for the changes!), they have since revised it further...and I'm sure this won't be the last time, so if you still don't like it, stay calm.
Feel free to check out the post about it here to see all this explained, as well as the rational feedback they have received and things they are aware of and are working to change. If you are ever curious, you can add
?ver=ngafter the URL for your profile page to see how the present revision would make your page look (for instance, to see mine under the latest revision, you'd go to http://archmage.livejournal.com/profile?ver=ng).
But, please...relax. It's the design process, not the apocalypse.
