how to update a blog page or add a new blog page in general? what is the right workflow?

Do i update the _posts/2012-08-14.blog.post-1.md file or the _sites/posts/ HTML file?

If you would like to add a new post, just add a new *.md file under _posts - the existing files there are examples of what the new post should look like.
