I never ventured into the proper forums there, only the comments on the articles. They’re clearly a lot tamer from the sounds of things, but from what I saw the outlook was always broadly one of not tolerating fools gladly.
El Reg has always been a home of snark: a site who for most of its life had the tagline “Biting the hand that feeds IT” is not likely to be all sunshine and roses, and for much of its life the snark was also very much the editorial line in its stories too. I can very well see how that might turn into a haven of what appears to be toxic elitism, but isn’t necessarily actually so - just hostile towards people who don’t necessarily align with their values, which doesn’t *have* to be the same thing.
