I personnally felt that, when a reefer comes to forum, learnt and shared knowledge. But there's a time where due to work committment, family matters (be it new wife(haha) new gf, new born babies) etc.
Maybe due to the above or some other committment which a reefer does not have the time to come to forums.
And could due to it's time to move on, gain enough basic knowledge for a basic tank, happy with the current tank and have not gone to the next stage for more difficult corals/fish.
Cheers
