Old fart here. I have plenty of experience with forums like Reddit, Voat, and the standard forums. I was even on the old dialin BBS systems in 1989 and ran my own for a while. But 8chan is not complicated, it's just different. There's no reply button, you have to click on the message number to reply, and there is no tooltip on that message number that tells you that's how you reply.  Because 8chan is a bit different it takes more effort for someone to take notes on how it works, but some people are just too lazy to take notes. As a programmer, I'm just used to taking notes when learning a new language, new system, or just writing down the variable or subroutine names for each program I work on. Taking notes has always been a big part of my life. But don't underestimate how lazy people can be.
