It really soured me against these sites to see the way they take other peoples' content and lock it behind a wall.
I just walk away when I see that stuff now. I miss the old internet that felt more like a public park than an amusement park.
At least on Quora, the minute you write something, it's Quora's content. As the user, I'm welcome to put my answer on a blog instead.
How is that any different from other social networks?
> With content being your secret sauce, you don't want to give it away for free.
Huh? Pinterest didn't even produce the content.
> Anyone can bookmark an image, not anyone can find the perfect image. Pinterest gives you that super power.
I have no idea what you're trying to say. What super power?
To illustrate; literally the first thing that popped in my mind when seeing this topic in the list was “Ah, that silly imageboard you can't view without signing up.”
