Comments on the Scalability of Facebook’s Social Behavior
An interesting points from a new Facebook study:
In other words, Facebook users comment on stuff from only about 5-7% of their Facebook friends. And as has been shown by many other studies, women communicate with more people in all cases than men.

The study also noted that people with more friends do not respond to more posts or chat to more friends.
I would propose that the true is not with end user bandwidth but their ability to consume the amount of data flowing through the newsfeed. I have noticed for example at 100 friends the noise level and attention swapping in the news feed becomes almost unbearable. The problem becomes even worse when the friend set is made of highly diverse clusters of people. For example if your friend set is 1) your family, 2) your high school contacts, 3) your co-workers, 4) your close friends, 5) previous co-workers. The issue is is there is little overlap between these sets of friends and this makes for a very cluttered news feed.
Optimally, your set of friends would be small, highly related and very active. Best case with the example above people from two of the groups both comment on a status update but typically they are both interacting with you, not each other.
A couple of options:
- Make the separate news feeds by friend list more prominent. It is currently hidden in the drop down and I admit I don’t get their very often.
- Direct the attention of the news feed based on clustering rather then just attention to particular people in the friend groups above. Perhaps Facebook is trying to make this happen but I don’t see it.
Final thought. Think about why so many users on twitter gravitate to the client Tweetdeck. I suspect many people have created groups to break apart their twitter friends using different tweekdeck panes. It is the only logical way to follow and interact with a diverse group of friends. Similar problem with a solution like number 1 above.




I have noticed a disturbing trend at work lately. We all have the same 5-10 short sleeve shirts in our closet! This week I had the embarrassing experience of showing up for a lunch appointment with a co-worker and we were wearing exactly the same shirt.
