A huge problem (as said above) is the spread that our community has on different social platforms. While its certainly allowed for more people to explore and discover our hobby, it has really spread us too thin as a community. When I was younger, I really used to hate the strict rigidity the moderation team kept in running the site. While nothing is wrong at all with how its run now, nor any other online forum outside of this, but the tight ship that Nerfhaven was made sure that content and conversation stayed on track and was useful for the community's growth.
Also abiding by the older rules of forums before reddit's rise is just too much work for most people now and is a turn off now that other alternatives exist. Information and posting is much easier on reddit and facebook, but you'll rarely ever see a composed writeup or build guide there which is why Nerfhaven remains a beacon to some in that way to easily work through the archives.
I just really wish there was a way for reddit/facebook and NH to coexist in a way where both could be utilized together, but theres too much overlap for new users to jump backwards I'm afraid.
