Nandemonai and @"Kimuzukashii MEIJI" : At the risk of taking the introduction board in a weird direction, the lower traffic is more a reflection of changes in Internet trends than anything else. Forums were the way people did most of their person-to-person and person-to-company Internet interactions back in 2005, and the great bulk of that work has been taken over by social media (especially Facebook and Twitter) in the intervening years. No matter what anyone here does, this forum will never be quite as happenin' a place as it was in the early 2000s again just because people's Internet consumption patterns have changed.
With that said, I think there's still several things that a forum can do that social media is poorly-engineered for, especially in the realm of detailed discussion. The sheer number of users you get with Facebook and the way it ranks comments by likes makes it really difficult to have a coherent discussion about much of anything on a company FB page. Its non-anonymity also makes it a weird place to discuss eroge--grandma and your uncle Steve may start wondering what this "nukige" you keep liking is all about. So, I think the board may be a bit quieter, but that doesn't mean it can't still be a great source of information and place for us to talk about our mutual hobby.
I would actually be interested in talking about ways to boost traffic to the forum, but if we do, let's start a separate discussion in the "Your Suggestions To Us" section so as not to hijack the introduction feed. Regardless, always good to see more familiar faces here!
I'd be interested too, we'd love to know your thoughts.
I belong to several forums that are great communities by themselves, but either don't have a Facebook presence or their Facebook group is a spammy, hate filled place with way too many pictures of cats. Maybe I've got a 2005 mindset, but I do love a well managed forum, particularly because of that sense of community I've never found on Facebook.
And then there's the privacy aspect, as you mentioned. A sense of privacy and safety does a lot to make people feel welcome. Here we can openly share our passion for Virtual Novels and Japanese otaku culture with other fans—it's a good place to be!
