Why are people not talking much on here?

Lack of fans I'm guessing. Most people that were once active and posting aren't active anymore. The fans that are active on the site don't post anything. I was around when the club was very active a few years ago but most of the people that posted content here are no longer around or just stopped posting altogether. Since there's such a lack of active users, some might feel there's no point in posting content since no one will really pay much attention to it.

It also may be because the Hetalia fandom doesn't seem very active anymore so people may have just moved on to other more active fandoms.
