No doubt it's large, but how many are spam accounts? How many are multiple account holders? How's it measured? Does a simple like button click count as an activity?



How many log in occasionally out of boredom, stare at the newsfeed for a few seconds, sigh, and log out?


Or rather, how many people are permanently logged in but never actually post anything on FB? For all we know, you might count as an active user if you so much as visit a third-party web page with some FB trackers on it.


Probably a lot, but those people still get advertisements.


Up until 2 months ago they had 8.7% of fake users http://news.cnet.com/8301-1023_3-57484991-93/facebook-8.7-pe...


"900 million human on earth actively uses facebook", is still an impressive number to boast about.


not really no. Compare to how many humans use the web or are simply connect to the internet, now that's impressive.

But knowing that many humans use the internet as a transport to a walled garden aware of their IRL identity and holding captive a heap of their personal data, this is frightening.


> not really no.

Please stop it.


If that number is still roughly accurate, it is a pretty impressively low number. I imagine that the average percentage of fakes/bots/etc. for web services is much higher.


0.087 * 900M = 78.3M

Roughly the equivalent of all of Germany's population (with 80M) being Facebook fake users.

Nevertheless I agree.. Impressive low number. Due to the scale of user base this still translates into a ridiculous amount of fake users


Actually, I think the scale is precisely what makes the number seem so low to me. It's a damned hard accomplishment to grow to 900M users while only picking up 80M fakes along the way.

80M is a large number, sure. But there are probably sites and services with 100M supposed users that have 80M fakes (some dating sites come to mind, as did MySpace in its prime). And I'm probably only exaggerating a tiny bit.


Won't they have to give a more detailed accounting of users now that they're public? Surely it's a very important thing to know if you hold facebook stock.


No. If they could make billions of dollars in revenue with just 100 users, that would be fine with investors.


So you're saying you honestly believe that how many Facebook users has is not important to Facebook investors?

Or are you just taking a valid question that was asked, "will they have to disclose their counting methods", and trying to start a philosophical argument about how to value companies? Because it looks like that's what you're doing.


The number of users implies that if they have more users, they will be able to generate more revenue. I'm stating i don't know what their future plans for revenue generation are but, in the end, that's all that's gonna matter.


Investors don't care, but advertisers do.


As long as their valuation depends on speculation, number of users matters.


Does it really matter? It's a number you can compare to other sites' reports of active users, doing the same measurements.


I think that, with this scale of numbers, the comparison isn't just to "other sites" but to the total population of Earth. That's why I at least find these numbers interesting.


Shouldn't this knowledge be researched and published for shareholders so they can weigh risks?
