Or put differently, what value will one user bring to a social network itself or to a third-party application running on a social network platfrom?
Take Facebook – Adonomics evaluation renders an active user value at $270. This is how much value user brings to Facebook itself.
It is a bit more difficult with third-party applications running on social network platform. I have seen different views generally ranging from $0.30 to $1.
What do you think?

I guess that can be as cheap as $0.
If you check facebook marketplace, you’ll find that smaller applications aren’t valued a lot. Asking prise for 2-3k application can be 300-500$, which makes it around 0.10$ per user. If application has more active users, it can potentially have better ratio.
There are extremes as well, there’s an app for sale 2k users and only 25$, which is 0.01$…

I believe the value of the user is directly related to what the marketer is trying to push through such sites. I don’t think Facebook is a valuable network yet with all the application distractions.

No freaking way. I
