Two things: folks care about Brew because its update story is nice; otherwise one needs to constantly revisit your /releases (or plug /releases.atom into their RSS reader) in order to know. It also offers very light "I got what I expected" behavior via their use of sha256, which your current setup won't participate in since you're only publishing .md5 anyway
That leads to the second thing which is that you said you "added binaries" but your release artifacts are .tar.gz which means that one now needs to `curl -fSL | tar -xzf - -C /whatever` and deal with whatever interior directory scheme you are using (I didn't check)
I suspect I may be throwing good commentary after bad, but if you did want to participate in Brew distribution, but don't want to go through their stupid PR process, you can retain control over your update schedule by creating a "Brew Tap" and then the consumer would (e.g.) `brew tap plutov/brew && brew install plutov/brew/oq` which also gets away from the naming collision
I also love Homebrew and use it daily, at the same time I don't want to go through the review process, but tap sounds good, will try it out, maybe goreleaser supports that too?
