You'll find a lot of FOSS developers on here. This is a general community and all that, but there is a large Linux and open source software interest here. Some people simply don't understand things like the scope of FOSS software in terms of both users and developers, so that can create some tension at times. There are a lot of experts and radical thinkers in this space. You may or may not find help on super niche questions, but say something wrong or poorly, and you're likely to find the experts soon thereafter. For instance, I am confident enough to ask advanced course computer science questions and get useful answers here. I find this place useful for second sourcing info from AI that I find plausible but sketchy. Like I got into fermentation but have no interest in the whole commercialized nonsense hobby junk. Almost all sources are poisoned by commercial interests and misguided nonsense. Just asking here gets lots of people with practical knowledge on fundamental techniques from long before it was some commercialized hobby.
The group behind the fediverse is very diverse and that diversity is reflected in the user space here in Lemmy.
