My experience so far with writing all my notes in public. 

For the past ~2 weeks I've been writing LessWrong shortform comments every day instead of writing on private notes. Minimally the notes just capture an interesting question / observation, but often I explore the question / observation further and relate it to other things. On good days I have multiple such notes, or especially high-quality notes. 

I think this experience has been hugely positive, as it makes my thoughts more transparent and easier to share with others for feedback. The upvotes on each note gives a (noisy / biased but still useful view) into what other people find interesting / relevant. It also just incentivises me to write more, and thus have better insight into how my thinking evolves over time. Finally it makes writing high-effort notes much easier since I can bootstrap off stuff I've done previously. 

I'm planning to mostly keep doing this, and might expand this practice by distilling my notes regularly (weekly? monthly?) into top-level posts
