Yeah, the internet is bigger now - all of the weird fringe stuff from enthusiasts is still there and there's even more of it. One thing that has happened is that the mainstream is there too now, so if you don't venture outside that its easier to not see the more interesting stuff. In the old days, when just having a "homepage" placed you a bit outside the norm, stumbling on something non-mainstream was more of a given.

And the mainstream has become more interesting as a result. It's not uncommon to watch anime now, D&D and video games are no longer niche, people's interests are becoming more diverse as media is no longer being gatekept by communities, geography or publishers, and everything becomes available to everyone. People might see that as a negative, the Eternal September effect eating their favorite thing, but I see it as a positive.
