1. Anki has search, tags and hierarchical organization.

2. If you don't remember that you already have something, it means Anki is failing you, because the whole point of it is to help you remember.

3. BUT! it doesn't really matter if you add the same note several times, it will just make it appear for review more often.

It seems like the value of the platform is in the well-classified data made by the community in the same way that emacs "killer feature" is the bazillions of community .el extensions. Is there a Github or some defacto standardized way people publish their Anki notes?

Do you mind elaborating a bit on how to do this well?

For example, I know it's possible to create a filtered deck which collects notes from several different decks. I can therefore use each deck to organize the different subjects and practice all of them by reviewing the filtered deck. Or do you mean the hierarchical-tag add-on? Or something else?
