A long time ago, there were users that would appear in the comments of every top post and they were almost always jokes. There were submitters that would reach the front page consistently. These people had essentially learned how to game Reddit, finding the right jokes and right material for their audience. And because of that, over the past couple of years it has became a race to the bottom in almost every subreddit and every comment. RES makes Reddit usable to some extent, but my filters filter out 75% of r/all, and what's left isn't very engaging.
The website has obviously outgrown me, and I have started spending most of my time on other sites now (sometimes even Digg). And it doesn't matter that Reddit lost me as a heavy user, cause I'm a nobody and Reddit will still get millions of views, just that Reddit meant a lot to me. It was the first website where I actually learned stuff. My Wikipedia usage went through the roof, reading up on things that people were talking about that I had no idea existed. Long articles and even handed discussions, occasional humor. I didn't comment or post a lot but I looked forward to getting lost in it. I miss it a little.
