Yep, only danger there is you dont have frame of reference and you get swept up into nonsense communities under the impression that it's what "most people" are concerned with at the moment, that's where the reliability part becomes so important.
I guess trial and error is an unavoidable component to obsession
Most subjects have an online community. It's a feature of the internet (or perhaps just social media) that these communities aren't all on the same platforms.
The hardest part is figuring out where the community is. Once you have a line on that, you can listen in and usually get a crash course on what you need to know just by following along with the conversation. I find that lurking for a while usually reveals where cutting edge stuff is happening (discords, mailing lists, real life meetups).
