Some statistics
I have a copy of the friends graph from a month or two ago. It's 842M uncompressed, 228M with gzip.
Some statistics:
1. Mean number of friends is 13. (More precisely, 12.95.)
2. Median number of friends is 5.
(The numbers are the same measuring "friends-of". That was obvious in the first case, not so obvious in the second.)
For friends: 10% have no more than 0, 20% have no more than 1, 30% have no more than 2, 40% have no more than 3, 50% have no more than 5, 60% have no more than 7, 70% have no more than 11, 80% have no more than 18, and 90% have no more than 33.
The friends-of numbers are: 1,1,2,3,5,7,17,32. I don't have combined numbers, though that might be an interesting statistic.
Here's some numbers (my total data, collected by crawling the LJ friends graph over the course of a month, had 2696203 people in it):
# with 0 friends: 299533
# with 1 friend: 414359
# with 2 friends: 263776
# with 3 friends: 193527
# with 4 friends: 155717
# with 5 friends: 129682
(For friends-of, the numbers are: 144064, 517753, 307090, 210998, 159798, 128749 respectively.)
The distribution of both of these is skewed. Here's a histogram using a log-log scale. I'm not used to thinking in log-log, but the graph is ugly and senseless without the log-log since it goes for the extremes. But here's a limited shot between twenty and one hundred.
Now, here's the big graph, a plot of friends-of (indegree) verses friends (outdegree). (I warn you, it is big. It has over two million points and takes a while to download and draw.) Here you see something interesting that sorta comes out in the other two graphs: there are more people with lots of friends-of than people with lots of friends.
Who are the extremely popular folk? Here's a list of the people with over 2500 on their friends-of list:
</a></b></a>doctor_livsy at 4601

</a></b></a>teh_indy at 2535
</a></b></a>drugoi at 2591
</a></b></a>foma and </a></b></a>fif are very friendly, with 1954 and 2219 friends, respectively. (I kept track of those with more than 750 friends. I think there may have been a policy change at LJ during my data collection, since there's a sharp cutoff in my data around 750.)
p.s. My data is out-of-date, but it probably is reasonably okay when it comes to trends. Also, while I did sanity check these results a bit, I won't swear they are correct.
