8chan was once just like that, a ghost town of a somewhat more modern AnonIB clone that wasn't really going anywhere. It owes its success entirely to the fiasco of Gamergate discussion being banned from 4chan, which caused a (literally) overnight exodus of a significant minority of 4chan who wanted to discuss it, along with those who (like me, in spite of the fact that I sometimes defend it on HN) were mostly appalled by the blatant abuse of power. These people weren't trying to "get away from" 4chan or its culture, they were forced to leave. They weren't curmudgeony "oldfags" or the like trying to enforce some new cultural norms in their secret club to increase the "quality", they were 4chan.
Perhaps not surprisingly, the site is now thriving as a community "for people who loved 4chan, by people who loved 4chan." And that's what's I love about it. It's just like 4chan, with a lot of the same people and ideas, but now, the community is running the show, not some guy trying to distance himself from "his creation" and a team of mods that often don't even use the boards they're supposed to protect enforcing arbitrary rules from afar.
Give it a shot. For all the negative attention that boards like /gamergate/ and /baphomet/ receive, they're in their own worlds. The rest of the site is very welcoming towards anyone that understands "4chan culture" and isn't obnoxious about it. Also, webms with sound.
This comment is exactly where my head is at and has been my connection with 4chan.
I had a very rough time in my teens, and my mother and I moved to new cities or towns every year or two. It was hard to keep friends and consider a place home. 4chan was the constant in my life where I could always escape to be comfortable and amongst people who shared my hobbies while experiencing free-speech without the repercussions of identity. No other site offers this like 4chan does, and I've seen plenty of other chans over the years, so, I'm skeptical about 8ch.
I know a lot of people who feel the same way. I'm scared for the future of what I consider my home.
