Ask HN: Facebook like. What's the significance of it?

[rymngh]

I read an article a month ago that discusses the significance of being liked in Facebook.

It shows that for each 10 likes, there's a chance that it will be read 3 times by their friends.

Now, I'm trying to find that article again because I want to re-read it.

Please if anyone knows the article, please point it to me.

Thanks
