I like the idea of a package manager because it's a central source for finding the applications I need and I can keep track of versions and updates very easily.
I recently downloaded and installed Anki. Their website's download section says this:
It's highly recommended that you install Anki from this package instead of relying on the version distributed with your OS, as the packages in the official repo are often very out of date.
This is the third or fourth application I've downloaded like this outside of my package manager. Why are the applications on the official repo so outdated that I have to do this?
