I use it in an academic sense. I use it browser plugin to one click capture a source. Zotero mostly automatically identifies the source type, author, and other metadata. It can retrieve metadata directly from files like pdfs too. Further it has ability to retrieve metadata from ISBN, doi, and other identifiers. It can export these sources to really any citation style and also integrates with other software for this purpose. It has a plugin system for extras too. I have nothing against text files on the disk but zotero is simply much better as a knowledge/source manager.
