I am indeed arguing that Facebook's very existence and the effect it had, insofar as it greased the wheel of Internet use, is a huge part of why Reddit can exist at the scale it does. Reddit is a better-organized web forum, which are not new, and maybe by its own design merit does it succeed. This, I do not argue with. But I do not think it could exist at its current or anywhere-near-comparable scale and level of success without the social network effect.
