Hello.
New poster here, but not new to the concepts.

I never use tags in DEVONthink.
5,000 documents; 0 tags.

Spend no time selecting tags, applying them to documents, or managing them.
I just dump everything into one DEVONthink database and let the software do the thinking.

I've been following this "no tags" approach for over five years now.
No problems at all.

Same for categories: none at all.
(Well, really just one category -- for a very specialized use.)

Result: minimal time, minimal effort, DEVONthink does all the thinking.

I wonder if any other DEVONthink users are doing this.
