People that stacked Roam Research
I've read my internet history, but I am ashamed to say that I had no idea how big a deal bidirectional links are. Roam showing me that was sufficiently big that I bought their true believer plan on principle, to reward them giving me the insight.
I love the simplicity of defaulting to a daily notes page combined with the power of effortless bidirectional linking. Encourages starting with writing instead of starting with categorizing. Organization is unobtrusive and naturally done as you write.
I am still very much in learning mode for this note-taking app, but REALLY like the bidirectional links, ability to reference other notes seamlessly, and overall power of this one make it very tempting. Price is a little high—$15/mo, though I got in early and am on a free plan.
