I've been using Roam, more-or-less daily since late 2019. Prior to that I had spent a lot of time with TheBrain as a tool for organising thought, before that there were others. I also spent a couple of years building a tool that Roam supplanted but that may, in due course, supplant Roam.

I would agree with the authors assertion that Roam is well suited to write-once/read-maybe. I certainly spend far less time reviewing notes than I ever imagined I would (that might be related to Roam's poor search/explore experience). Where I diverge from the author is that I find the Daily Notes page answers the question of where do I put this?

I have a daily notes template that includes headings:

TODO

Talking With

Found This

Thinking About

Working On

Completed

Every day a new slate, but ordered around the same core principles. At each heading I use tags, for example under [[Talking With]] might come a heading [[Some one]] & [[Someone else]] from [[Foo Corp]] and then proceed to take notes under that. If I can I will [[topic]] things but if the notes are contemporaneous that can be difficult. Under [[Thinking About]] are any of a set of headings I am current musing on, along with a fragmentary thought I just had. If I ever do review I most likely jump off from the [[Thinking About]] tag.

This allows me not to worry about where to put things but, for example, I can usually find notes of sessions with clients quite easily and branch out from there if I want to follow a train of thought.

As time has gone by I've found the product remains useful although my hope for it and the company is not high.
