No. Facebook does not charge publishers for a share/post to Facebook button. Here is the official link: Share Button. On clicking on “Get code”, you will get a code snippet that you can include for free in your website. If a user decides to use a “Share/like” button, that is a win-win for both Facebook and the publisher, and it does not make any business sense for Facebook to charge for this feature. 
In fact, on Allrecipes, if you wait for the full page to load  (The page load time is definitely more than usual.) , you will see the FB icon appearing in the list of social plugins.

I agree with this!  When it comes to friendship, I have always been a “Quality over Quantity” guy. I have always had a few very close friends, and a lot of acquaintances, and even a guy like me has 800+ friends on Facebook! And that’s not a lot: the last I checked, 94 of my friends have 1000 or more friends!

1000 friends! Is it possible for someone to have 1000 real friends! Studies suggest that there is actually a limit to the number of social relationships one can maintain, and for most people, the number is somewhere between  100 and 230 (150 is the commonly used number) This is called Dunbar’s number named after British anthropologist Robin Dunbar, who did some research on this topic. (Read more about this here: Dunbar’s number)

But Dunbar’s analysis is from pre-social media days. (His article was first published in 1992) Is it possible that with the advent of social media, the mankind has suddenly become more “social”? Apparently not! Read about this guy’s attempts to take on Dunbar, or may be try your own experiment. Either way, I am sure you will come up with similar results!

The cartoon strip below is profound and funny at the same time, and sums up everything I have said above.

But I also need to think of the features that end-user will not normally think of, and also the ones that will make Facebook some money. I have one […]

Some time back, I had applied to a startup for a Strategy intern position, and as a part of application, I had to answer some interesting questions. One of them included what would I like to see in Facebook. I didn’t want to delay the application, and submitted whatever I could think of in 30-40 […]
