Why would anyone pay for Facebook? I'm using facebook but I believe it has negative value. It's a bad habit like smoking. You understand that it is bad but it's not easy to quit.
If they start charging money for fb access it will make it very easy to drop this bad habit and quit Facebook.
Cigarettes are becoming more expensive with every year and it made lots of people quit smoking.
I don't have the willpower to stop browsing facebook and instagram from time to time. But next second they announce paid access, I'll stop using it.
Although even without this, I find myself browsing Facebook and Instagram less frequently with every passing month. At this rate it would be rather painless to quit it altogether by the end of the year.
