Facebook lost around 2.8M U.S. users under 25 last year
Facebook suffered from 2 waves of <i>"Eternal September"</i>[0]:<p>wave 1:  the addition of <i>everybody</i> outside your immediate friends and close family.  You get the goofy uncle, the  distant high school acquaintances, and all the work acquaintances from every previous job that submitted a "friend request" that you didn't reject out of politeness.  The newsfeed gets polluted by nonsense such as forwarded memes, politics, and other junk.<p>wave 2:  the corporate advertisers filling up the newsfeed that crowds out the desirable posts from your real friends & family.<p>The 2004 to 2008 period was probably the "magical" time for Facebook from a user standpoint.  The initial wave of Harvard students had a beautiful user experience with TheFacebook.  As for the new members joining Facebook today in 2018?!?  Not so much.<p>Of course, ads are needed to pay for the datacenters so any social network like Facebook inevitably decays into a worthless waste of time.<p>[0] <a href="https://en.wikipedia.org/wiki/Eternal_September" rel="nofollow">https://en.wikipedia.org/wiki/Eternal_September</a>
