I think there's an important nuance separating "personalized" and "tailored". The personalization the article is talking about is mostly geared towards deciding which sources someone should see--do you want to see stuff from Drudge or HuffPo, for example. Imagine if Pandora only played stuff from bands that it knew you liked.
Tailoring a feed to someone's interest, however, is more like what Pandora actually does--learn "what" you like, not "who" you like. So I've discovered a lot of musicians that I would never have otherwise heard from Pandora, which rocks.
I think a tailored feed that keeps my interest and exposes me to new things that I'll actually be interested in is the best of both worlds.
