My take on this is; back in the day when Facebook and to the extent Twitter were dominating so called "social media", being on Facebook or Twitter meant that you were actually connected with all the people who wanted to be a part of social Web. But today, social networking is so fragmented with dozens of social sites, mobile apps, fediverse networks and who knows what that I think, we are actually going back to the time of decentralized and distributed internet forums where people would gather in small communities and connect with each other, which is not necessarily bad because all the power is not concentrated in Facebook and Twitter but then again all the interesting people are not in the one place but in the 10 different places hence Zuckerberg stating that Facebook started as a directory of people which was meant to centralize all people and their connections in one place.
