I am checking it out. 30 years ago I interned in DC. The owner, a previous school teacher, was not directing education programs about government. She had files and files of news clippings, notes, and papers that were organized in a fashion that I don’t remember. But for her, she could find anything. With all of my experience, I have filed stuff in the categories and am pretty sure I can not find a thing, and due to the useless savings, a few years ago, I deleted it all and started over. Application of Tags was my first attempt. It was helpful. Now we are here with bi-directional note taking and I think there is more to come.
