Not only is this a repost, I have seen it on Hacker News several times over the past year. Anyone who is searching for a better Git log will find one without the help of free advertisement on the front page.
Many git novices don't know that the log output can even be changed, and aren't likely to be searching for an alternative syntax. Don't assume that just because you know something, everyone else does, an that the training is useless.
Additionally, the discussions that this post created here in the comments have already given me three new aliases that I didn't know we're possible.
clearly you're not very imaginative. not thinking or realizing you can change the output is naive. there are so many people writing up the same hints it's almost impossible not to run into something like this daily. if you seriously rely on 'discussions' to improve your knowledge you're not really thinking for yourself, are you?
