Biggest reason it is like that is because it is a massive time sink for very little gain. Lead admin is a med student, many other site leaders are enrolled at universities or pursuing careers. There were many large projects in the works, but because the site admins work for free (Fuwanovel operates at a loss even with donations) there is very little incentive to dedicate hours upon hours creating content that would fulfill the many goals this site has.
For example, most of the steam curation team has left to do other things with their lives. I and Palas had been working on a project to create an OELVN update tracker, but the amount of time we put into it was pretty heavy, and on top of that, half of the OELVN teams I contacted never once got back to me and hid updates behind a kickstarter paywall.
Perhaps the biggest obstacle facing Fuwanovel is that the leadership that does stick around and loves VNs ends up going to work in the VN industry to actually get paid.
The simple fact of the matter is that Fuwanovel is at this point simply a community with popular VNTS updates. I highly doubt any new projects are in the pipeline, so the site is in a what you see is what you get phase. It really is difficult to dedicate time to building these projects while neglecting a million other things in your personal life that you would rather deal with.
