@gabecolors, ah I see. I don’t know of any downloadable vaults (although it kind of rings a bell that there were some of those around here as well; getting too late to try search for it…). But I think many of these published vaults are close to their “original” – they really are vaults, just published. (There are a few things that don’t work on Obsidian publish sites that otherwise a lot of people use – basically, none of the plugins work. Dataview is perhaps the most important one. But you can get along without these in your vault as well.)
So at least you can get a sense of how people link things, what kinds of notes they have, etc. But it all will vary really much depending on the specific vault you’re looking at.
My takeaway from the year-and-half of experience I have had with Obsidian is that you’ll have to develop your own system no matter what. Sure, looking at examples may be helpful, but you have to do what works for you. And it will evolve, and that’s okay too.
