We noticed recently that people didn't like it when Facebook experimented with their news feed. Even the FTC is getting involved. But guess what, everybody: if you use the Internet, you're the subject of hundreds of experiments at any given time, on every site. That's how websites work.

Because the way love works in general, you don't need everybody to like you somewhat - you need one person to like you a lot.

Kind of paradoxically, men are very open minded or very even handed with their votes of women.
