Imageboards in general have lost their appeal to me. They're little more than a news source for me now. It used to be about letting loose, shitpost for fun, occasionally toll and if youre lucky end up in a stimulating debate with others.
It's just interboard drama and complaining about real world events now. Everything is politicized, rules prevent spontaneity, and everyone, including seemingly pro free speech /v/tards and lolifags have turned into a bunch of hypocrites. Even more so than they were.
I believe the main aspect I'm missing is boards being a melting pot of a bunch of different people with different worldviews. Every board subculture is heavily segregated and locked into a tight set of believes that you have to either pretend to agree with or get ad hominem'd out. The most fun on boards I had recently was on short lived ones like 10 and 9chan, which despite their cp spam, which some argue is a part of the original chan culture, had a spirit of innocence and reckless fun on their /b/ boards. The reason for that I think was that the rest of their sites were dead, so everybody congregated on /b/ for interaction. I dunno, I really enjoy being part of that kind of randomness. For a few weeks it made me feel like I was back in 2006.
