I have more useful conversation on "dead" sites like this than most active imageboards tbh:
There is often very relevant or useful information given for a particular game. Sometimes I answer questions that are a year or more old, and even get replies some months later. But I don't check for this constantly, and a lot of time can go by before I find out. However, the conversation exists and it's useful for someone.
On some sites you need to register a username before you can post, but it's the same concept:
On this chan and most others people only talk about boring new games or mostly other new stuff I don't care about one bit. I get *more* out of those slow sites than here. I'm basically the only one that posts about old computers and games, and oddball hardware like ARM boards. Even on that nanochan that's on Tor, most of the stuff people post is disinfo, totally bogus stuff. I guess it's a bunch of trolls or shills, or whatever. But it takes energy and time to debunk their lies, and ultimately I don't get anything out of it. It's really just a waste of time that I could be spending on other things I actually enjoy like games and other computer stuff from before Win95, or learning something useful I can apply later on since I've got projects I want to do.
