Uh... and you think that ridiculously misleading title is anything other than a press release? The "it sucks" comment was thrown in as an afterthought.
"Facebook unveils one of history's most powerful recommendation engines"
This article is an attempt to garner eyeballs by making a loud statement full of dramatic words ("unveil", "history", "powerful") at a time when Facebook vs. Google is considered a hot topic. Nothing more.
This article is a supposedly impartial discussion from one of the web's (supposedly) informed sources that consists of nothing but value judgments. This article, though it rambles mightily, manages to say almost nothing about Facebook privacy issues, nor does the author seem to be aware that the few "recommendation engines" that exist share one thing in common: they all suck, they don't inspire users, and nobody has figured how to change this. Including Facebook.
So when I say it's "misleading", what I mean is that what the title promises, the content doesn't deliver. The headline reads (no offense to the author) like a high school newspaper editor's first attempt at a headline that "grabs".
