The website you posted has nothing to do with PPA's. The only real site for information on authentic PPA's (not just repos that some people call PPA's) that I'm aware of is launchpad.net.
And as said below, there are potential problems with using PPA's. You definitely get newer versions, which is sometimes useful, but it's a use-at-your-own-risk type of situation. I've had PPA's completely backfire on me. Also, primarily using 3rd party software sources brings potential stability and security risks. They're there, and you're welcome to use them. But I wouldn't base a distro on them.
Apart from being nonsense, this appears to be an attempt to direct readers to a commercial website unconnected to linux
The use of ppa means a shift to more or less unsecured and unsupported software. This is a choice each person can do, but as a distribution aimed at "the average person" it is not responsible.
