I think there's some nuance to this. In general, people who spend all of their time on one site is dwindling as information becomes more available in more places and is crowdsourced on social media. However, these more localized groups can still succeed because of the limitations on the larger social sites.
With CGN I don't think the owner has the energy or commitment to rebuild the site to where it need to go. Starting over and opening up registrations isn't enough IMHO. As mentioned with community focus, the focus there is no longer on 2A and more historical data and current politics. That being the case, this site is seeing consistent month over month growth as people continue to hear that there's a California specific site to help new 2A enthusiasts get onboarded without being judged. Also we try to keep the format minimal so topics don't get drowned out. Social I consider as short form content, there's still the need for medium and long term content which is the void we're trying to fill.
Youtube & Instagram are persona/influencer led. Facebook Groups and Reddit are more community based like here, with FB you have to use your real name and with Reddit it's complete anonymity. What we're aiming to build here is the middle ground. On the large platforms all your data is harvested. Here, we try to make it as private as possible for members with only limited data available to the public for viewing. We don't grow as fast, but that's not my priority. The site IS fast and lean and shielded from a lot of scanners, which can be objectively seen with the low number of guests viewing the site. The feedback system here is also a key point for people returning. None of the big platforms really have that for their users.
Once the platform is upgraded and migrated, we'll focus more on getting the word out to people to hopefully grow this community with similar energy & spirit of how I remember CGN used to be. We're building a shooting team and will be hosting events. Hopefully I can find some people to help out with that. 2A is continuing to grow in CA as more people get P.O.'d with the state of the state. The members from 100-12,000 have continually helped to improve the site and I'm still taking input. As the site grows, it becomes harder to change things as you've seen with CGN, which is why we do a lot of front loading and constant upgrades.
