It will be a vicious circle like we're currently seeing on twitter and Facebook, where we can still be considered early adopters, and if the newer/younger people pick this over Reddit we will reach critical mass easily. Main issue will be on boarding the next generation of users here instead of Reddit .
Not wholly unrelated, I've noticed a massive uptick in NSFW content, both OC and reposted, and historically that tends to be a good indication of where people are flocking to.
