This will get downvotes here, because many HNers somehow see value in Twitter. But I'm actually surprised that many people would bid on Twitter at anywhere close to its current valuation of ~$17 billion. Here's one reason why: Go ask any major affiliate marketing network how they feel about Twitter traffic. Many of them have an outright ban on it - meaning it actually has negative value to their advertisers. It simpl…

Even if the average for Twitter users is low, there are probably pockets of value for particular services. These are potentially not the kinds of customers these affiliate networks are interested in. Your Android point is rather different, given the wide disparity of Android devices. If 80% of Android devices are wo…
I disagree that it's different. Of course there are pockets of both value and worthlessness everywhere, but overall the LTV of an Android user to developers and advertisers is a small fraction of that of an ioS user, and a Twitter user is worth (to advertisers) an even smaller fraction of the value of a Facebook user.
At scale, averages are what count.

I did notice that, and I cannot disagree with you there. But currently, for many advertisers, last-click based means is the most efficient available attribution model, even though I agree that it's far from perfect.
