haha wait do you actually read long commit messages( more than a line) all the way through? like line-by-line, imo commit msg = tweet, git note = blog post.
Most of the times, the commit message is 10+ lines while the change itself is -1/+1.
We use GitHub for repo hosting and a separate issue tracker to coordinate changes. It bothers me a lot that GitHub UI doesn't render markdown for commit messages. We all write really detailed and nicely formatted commit messages, and had to work out a commit message sync so the issue tracker can display related commit messages in full Markdown glory.
