I think to anyone who has used it, it is plain testament that social networks do not scale. This is a social limitation, not a technical one. What killed the Internet is the centralization of platforms compounded by the commercial interest to "engage" on behalf of both corporations and users. IRC worked because it was decentralized and had no commercial interest, nor did it cater to narcissistic tendencies. No interest to comment for points, and decentralized enforcement where you'd fuck around and simply get banned from the(that) server.
