> Homebrew is much closer to that rolling always-up-to-date (within a day or two usually) experience than Apt or Yum on Debian/Ubuntu/Fedora (most people's linux experience), where you have a choice between packages that are 3-6 months out of date or hunting around on the web for a 3rd-party repository to add which contains more up to date packages

It still has a centralized list of the versions of the packages it supports (on github) though, right? I feel like it should be able to get this list with a single HTTP request to the Github API; I don't see why having a faster or slower schedule to update the packages should affect how long it takes to actually download the list of updated packages with `brew update`.
