Really excellent tool, especially for long-form note-taking. The user interface has an overall elegance that makes this tool stand-out. It would be five stars if the developers truly respected user freedom by making Obsidian open source software.
Obsidian is by far the most valuable product I interact with on a day-to-day. I've been using it since the beginning and the evolution of the community and product is so beautiful. Obsidian is quite literately my second brain until I die.
