Not gonna lie, I'd be pretty bummed out if this place decided to shut down. It's one of the few sites I visit every day, I enjoy the community, I've met some people here I can genuinely call friend, I can say what I want to say or joke around without worrying about being banned or having my personal life ruined. This place is one of the last bastions online you can truly call a community.
That said, I get where you're coming from. If you're not happy, Null, it shouldn't be your cross to bear to keep manning the controls if it's not fulfilling for you anymore. At the end of the day, you gotta do what's best for you. I'm sorry to hear things aren't what they could be for you, and I hope that can be remedied soon. For what it's worth from a relative newfag, I think most people here would understand any decision you come to, at the very least, most people like you and respect what you've done with the site. You gotta watch out for yourself though, whether it's just taking a hiatus from the site, deciding to close it or hand the reigns off to someone else, we understand. Hope things start getting better.
