I've been heavily using obsidian lately. The notes helps me writing blog posts immensely. Some posts wrote themselves. This very post was wrote on obsidian too. I figured it's easier to write and publish the markdown files directly.
I own my data
Most of my data are stored on somebody's server. And I either am okay with that or do not care that much. But the notes and blog posts are very personal things, so personal that I stopped entirely trusting some companies and store all my posts there. I wanted to make sure that if for some reason all my accounts are not accessible anymore, I still have all my posts.
