There was point, years before the v4 redesign, where 90% of the content hitting the front-page was supplied by 100 or so so-called "power users". Of that 90%, probably 40% was supplied by Mr. Baby Man himself. Hitting the frontpage was an impossibility unless you went around friending other users and building up your network. A worthwhile investment if you were doing social media professionally but for the average user they had no voice except in a comments section. After I realized this I moved onto reddit and never looked back. Of course reddit has suffered it's own unique set of consequences from becoming the kid on the block.
