It is unequivocally Facebook now, both Twitter & Reddit are a barrage of Facebook users and it shows.

Reddit literally made their newReddit interface to look like Facebook, because their users are worth more money. Spez knew that Reddit would turn into a copy of Facebook, quality and all and decided it was worth it years ago.

The Reddit we used 10 years ago, the one with it's own unique culture, is half dead and it's only going further in that direction.
