I am with you. I have been using Obsidian for the past couple of years and it makes me happy. So happy that I was blathering on about how awesome it is for a paragraph or two here, but I realized that was not necessary.
Nevertheless, it really does provide a great way to take notes, allowing me to instantly create new pages in a wiki-like fashion, for details on application X or technology Y and so on.
I wish I had apps like this in college.
