If you try to create a Google account from Google's homepage, you'll notice that Google redesigned the page, but that's not all. You'll now have to create a Gmail account, a Google Profile and you'll automatically join Google+.
Until now, creating a Google account was quite simple. You could either use an existing email address or create a Gmail account. The redesigned form includes new fields: name, gender (required for Google+) and mobile phone number (not required).
