1. There are 1,225 Facebook applications available in the Facebook directory.
2. There are 73,109,074 installed applications in Facebook users' profiles.
3. Hence the average application has about 59700 users.
The problem with the average is that it hides a savage reality of Facebook applications: some have many users, most have almost none. To analyze that I broke the data logarithmically counting the number of applications with greater than 1,000,000, 100,000, 10,000, 1,000, 100, 10 and 0 users.
|At least X users||Total applications||Percent of total|
So, 86% of applications on Facebook have less than 10,000 users, with 62% having less than 1,000 users. The 'big applications' (with over 100,000 users) account for 5% of all the applications, and only 2% make it over 1,000,000 users. So for most people developing a Facebook applications means very, very few users.
Graphing that you get a classic Long Tail picture:
The top 21 applications (over 1,000,000 users are):
|HOT or NOT||1,138,625|
|Where I've Been||1,027,373|
Another way to examine the Facebook data is to ask who the most prolific authors are. The top most profilic authors are:
Only Kevin Koder (with 230,164 users spread of 8 applications) is anywhere near being a 'top application' on Facebook. Kevin's top application is Family Guy Quotes.
The top 10 authors by number of users are:
|R. Tyler Ballance||4556234|
Unsurprisingly Facebook is one of the most popular authors given their advantage of actually owning the site. Ignoring the companies on the list there are a few individuals who've hit the big time on Facebook. Whether that turns in to any money for them is another thing... but Facebook benefits from this Long Tail because the cost to them of the vast underbelly of barely used applications is close to 0: they don't even host those applications, you do.
