I was lurking around the Google+ settings panel. Unlike the early days of Facebook, Google+ defaults to sensible privacy settings. There weren’t that many settings to look at. Instead, the more interesting section of the settings panel is what appears to be the future of Normal People™ account settings.
On the bottom of the page, it says:
Looking for older account options? Visit the previous version of the Google accounts screen »
That links you back to the old confusing service-centric layout.
Normal people don’t need to see all that extra-stuff. They just want the basics – like every other website, a single simple place to change passwords and set email address. At the same time, as time goes on and Google expands on the list on the sidebar to contain settings for other services, it’ll probably end up looking somewhat similar, albeit less spaced out.
