Thanks. i did read some posts. In the end, I just need to move forward and try it out.
My use of Devonthink is mostly as a wiki, to keep information related to some subject I like organized, like music, health, running, chess. I did buy “take control of Devonthink 3” and started to read it.
Not to spend your money for you … but Kourosh Dini’s recent book might be a good guide for you for “how to keep information related to some subject”. It is well organized and helps both with useful thoughts on note taking and gathering and organizing information with DEVONthink
