For MANY things a simple text files (txt, tsv, gnu recutils, ...) is required. Using the filesystem (folder, links, ..) to organize them.

I started moving back all my things/KB to simple text files and stop using all apps/web apps "du jour". Using text files is SO lightweight and resource efficient.

For multimedia content, I use only open/future proof format free of any patents/legal restrictions.
