It just grew, caused by managing a big scientific project. Whenever I learned some technique or something outside of obsidian (i.E. Kanban, Zettelkasten, journaling,…) there usually was a way to make it work in obsidian. Sometimes with some fiddeling. And sometimes obsidian just provided auxiliary information and structure. At no point i was feeling restricted by the software. So there was never a reason to ditch or even question it.
I do have backups on a personal nextcloud (and thus multiple systems) and a homeserver. Phone is a no for me, because i need big screens. Also nextcloud sync is fucked on phone and i am to lazy to properly setup an alternative. But that’s not a problem caused by obsidian.
I think Obsidian is a tool, that is so good, it works like an OS. I’d even go so far to say, that it is the alternative to my data-explorer. So almost every navigation on my machine can work through Obsidian. The Plugins are just extending this tool. Which Plugins i use depends more on the externalities. But i usually find a plugin or way to make it work. Though sometimes there is some highly-specific thing i cannot achieve in Obsidian, it’s still fine. Because it can act as a hub.
For example I make my budgeting with MMEX. But i have the file in the obsidian vault. And a lot of auxiliary data is in Obsidian, contextualizing this database. For example files with the reasoning behind the budgets or investment strategies. I always have some benefit from connecting things to Obsidian in some way.
I put everything in the vault. My redundancies make it very unlikely that i lose data. From the data-security-standpoint i have no reason for not trusting obsidian. For the plugins it might be sensible to think about data-security. But ehh… I use AI with access to my vault. I use google. So even if it were an issue, Obsidian (and its plugin) would be negligible in the grad scheme of things…
Also compared to before, i have no local duplicates. I used to copy a file to a different folder “for backup”. You think i know which files i worked on? I only have this problem when working outside of obsidian. (Also git helps in the worst case…)
I decided to keep my work and personal things in the same vault. But within it, the content is separated. So if need arises, i would be able to split it within a couple of hours, without sacrificing any usability. (A weird architecture, based on 1 “Mainvault” and up to two logical vaults, achieved through syncing). But with my current employer there is just no reason to split the data. So i do not see any need to do it right now.
Yes, i think it’s about “what im i comfortable relying on”. To me, it’s highly dependent on control. At no point i had the feeling obsidian was the reason i was not in control of my data. Usually it’s because i fucked up, i was to lazy to properly look for plugins or something different external. And even if obsidian stopped existing… It would just be a tremendous inconvenience, but I’d manage. Just by switching to a random coding environment, i can maintain the core usability until i find an alternative.
