I started browsing NG actively around 2009-2010. Back then the NG already felt like it had best days behind. Already back then the NG lore was vast and incredible. But beside discovering the vast back catalog of NG, you still had not only incredible daily content for both games and animations, but also interesting creative personalities, which you wanted to follow.
For me the end happened with Africa Dudes collab - I even wrote a review there, which sums up my feelings. When I created an account in late 2014, it wasn't to be active on NG, but because I wanted to read Stamper's rants under his art again, which I couldn't do without having an account, because his art was A+ rated, which meant that it was hidden from lurkers. Already back then I treated it more as a nostalgia and a farewell matter.
Since then, the NG got some fresh blood, but frankly, I don't really care. I started collecting medals, because I thought that I will be the best medal hunter again, and surprise surprise, I was right. Nowadays I'm mostly on NG for some online games, and I don't care about anything else tbh.
There are still some interesting people, and you can compare how NG changed with the Faces of NG submission, as well as the new version, which is a tribute to the original. There is still good stuff here, but there's no point in treating NG seriously, and more importantly, social media are cancer, and internet communities are awful. Everywhere, whether it's 4chan or RYM, it just bleh.
Also, NG has probably the worst taste in music in the world. I have never seen more pedestrian, dumber, and shittier taste in music, than on NG. It's like people here are beyond super retarded. For that alone, I will never treat NG seriously. Ever.

As someone who was here since around 2001, hearing someone be nostalgic about 2012-2018 Newgrounds is kind of funny.

Yeah, you're a bit older than I. 2012-2018 Newgrounds is what I grew up with. I even remember when you actually had to wait for Dad N' Me to load before you could play it. Now it's instant. Which is not a complaint. But I also miss the anticipation of waiting for it to load too.
