I’ve been a happy user of Obsidian for almost a year. It’s a solid product, moving at impressive speed (until recently they had almost weekly releases of features/bugs/improvements) with just 2 people. In my opinion we need more products and teams like these.

As for my use of Obsidian, I’ve put into it almost 400 permanent notes into it and I have my journal in it as well. I find the process of connecting ideas and thoughts great for exploring subjects/books/articles. I’m a fan of this product.
