The learning curve is so steep you might want to drop it at the very beginning. But don't be deceived! Once you get a hang of how tiddlers work and set up a system that matches your workflow, the payoff is crazy

Obsidian is seriously the best note app even regardless of whether or not you use "second brain" features. A huge advantage is always having your notes on the device. Want to back up? Easy! Want to sync? Do it! Need to print a specific note or send it over? No one's stopping you!
