I work for an online retailer for computer components. Reddit helped/helps give me perspective of what people think about tech products, what they're looking to buy, and I used it to keep up with the news in the hardware-focused subreddits. Reddit's community is sufficiently large enough that there are opinions you can read from enthusiasts to homelabbers to people who don't know what to do when Windows screws up their Radeon Software installation.
As a former technical writer, it helps fill in gaps about things I don't know enough about, like where people on lower budgets actually choose to spend their money in a build, and whether or not the RTX 4060 is actually terrible, as opposed to it not meeting expectations of an audience that it's not aimed at.
I feel like most of the useful Linux stuff just got yeeted from forums and into Reddit. If there's nothing in the Arch wiki that's easy to follow it's a trying time to find answers that relate to your issue that are also up to date.
