Oh I like the web version!
I just hooked up the web app to my _public_ blog repo, and started editing the markdown files. Hit save and it automatically performs a git commit on my behalf. Perfect. Next time I'm working on the files locally, all I need is a git pull and I am good to go. I like it.
Although I didnt quite like that it asked for a permission to pretty much _everything_ in Githuhb - public and private repos, deploykeys?!, everything. I wish that were customisable. It was okay for me because I dont keep any non public code in Github, but others might have..
