What I've been noticing these past few years is that Nintendo-related content has been taking up more and more space on VGC. I remember the first time I became aware of it was back in 2016 where every Nintendo fan and his mom were making duplicate threads about Switch and BotW rumors.
While that in itself is perfectly fine and somewhat natural considering how awesome the Switch and its games are doing, I think that it limits the potential and appeal of the site. People dropping by searching for PC/PS/XB-related content won't necessarily stick around for long.
You could say that a solution would be for people to start making more varied threads but I simply don't think that VGC has the number of PC/PS/XB-leaning users required to create and nurture such threads. It had 3-4 years ago but not anymore.
As of this writing, only 2 out of 14 "Hot topics" (VGC's bread and butter) are related to PC/PS/XB. The rest are made up of 6 Nintendo-related threads, 3 NSFW, 1 political, 1 movie and 1 general thread.
