Trying out a couple of features at once. I’m posting https : //gist.github.com / 795682 (without the spaces) on its own row in the posterous editor. Since it’s showing a gist, it means the blog post http://blog.posterous.com/posterous-now-supports-traileraddict-embeds-a did not lie. That’s a good thing. Now read the gist :) It basically says that you can edit anything you’d like and post it as a code snippet (or “gist”) to github, from within vim. It will save time.
