Most importantly, Facebook provides *immediate* value which Twitter does not. And, because of network effects, this immediate and lasting value is likely to continue to increase.

When somebody who I am friends with on Facebook follows me on Twitter, I always check to see if they meet one of the above criteria before I follow them. Whereas I'm interested in the life of pretty much everybody I know (even though I'm, as expressed previously, interested in some more than others), so it's not really “less” special to be my friend on Facebook. Actually, on average, I probably pay way more concentrated, direct attention to a friend on Facebook than on Twitter. But because the aforementioned attention is more intense and time-consuming, it happens less frequently.

If they eventually want Facebook to become ubiquitous in our lives, they're going to have to realize that the advent of technology to support very large networks means that people will want to keep track of the thousands of friends and contacts they accumulate as their life progresses. I have my classmates from preschool Facebooked, as well as from middle school, high school, and college. Not to mention my friends and colleagues from study abroad programs, jobs, and different cities I've lived in.

I may be a fringe case now, but if their growth continues, I won't be for long.

But yeah, they may end up driving some people back to Myspace or something, especially if they don't get the quiz app spam under control.

Being one of the most addicted (or, as I prefer to say, “prolific”) Facebook users of which I know or am aware, I have to say that my addiction stopped cold as soon as the newest version of Facebook was launched. Because they decided to put the focus of the service on “WHATSHAPPENINGRIGHTNOWTHISVERYSECONDOMGOMG” instead of “a self-managed digest of the recent events and news in the lives of my friends and other people in my life.”

The “live” newsfeed is flooded with status messages (usually duplicated from my Twitterstream) and results of Facebook quiz apps (aka absolute shit I don't care about and never had to be exposed to before), all inevitably from the people in my network that I care least to actively follow. I realize you can make “lists,” but using them feels clunky. I much preferred the feature they had before better, which allowed me to just give them a list of people I cared most about seeing in my feed, and then let them add in other activity based on their internal algorithms of “interestingness.”

Most of all, I'm so sick of seeing my own avatar all over my own wall. On my profile, it's difficult to tell what is my activity and what is other people's activity. Furthermore, “equalizing” the activity on people's individual profiles has made everything look flat and dull.

The bottom line is that not alll activity is not created equal. People have different preferences when it comes to activity, which they used to be able to express. Now, all the activity I actually care about is minimized and sterilized. For instance, pictures no longer stretch across the profile, nor do videos. And I can't change the size of status updates, to put more emphasis on ones that are important to me.

I go to Facebook to bear witness to people's lives, not to see all of their dynamic content marginalized to the pithy size of a status update. That's what Twitter is for.
