It's pretty safe to ignore most of the flack in this thread. Most people vote with their feet (or wallets, or eyeballs, or attention), and they've voted that they love Facebook, regardless of what a minority of people in this thread say or upvote.
Nerds have a cantankerous side and are as prone to virtue signalling as any other group. Those of us who read Slashdot ages ago may remember the Microsoft hate it hosted and the way every year was going to be the year of Linux on the desktop. Well, Microsoft is still here; Linux on the desktop is still a minority pursuit; and most people never cared that much about the OS they used.
The specific target nerd derision has changed some, but the form of the attack and disdain has not. Any company or country or person's haters is proportionate to its size. Look at what people do and how they behave rather than what they say.
