While we’re on the topic of Clojure being useful…
I use git flow for all my projects. It’s relaxing to know that, even when you’re working solo, you have zero chance of screwing yourself over because - say - you need to make a hotfix but can’t because of a dirty master branch state.
In some projects like khroma I’ll use major/minor version for the release numbers. But in a lot of cases, like this very site, there’s no concept of a major or minor release - you just want to time-stamp each one. I may even need to start several releases a day.
I wrote a small ClojureScript helper to remove the chance of human error.
