Unlike reddit, 4chan is not a popularity contest. There are no likes or upvotes that dictate what you see; everyone in a thread sees the same content. Furthermore, there are no persistent identities, so you have no way of gauging the value of someone's post other than by examining its content. I think this dynamic is what made 4chan such a creative force: the only way for a post to "live" longer than one thread was to make it memetic, remixable, broadly applicable.
What I really like about 4chan nowadays is the pace. When a new episode of my favorite show is out, or when the Super Bowl is on, or when a presidential candidate says something stupid, I know there will be a thread about it. At times, it's almost like we're all in the same room together. Having browsed for 7 years now, it really does feel like home to me.
