Using sparse-checkout to work on part of a git project

While working on redesigning this site, I thought that it would be nice if I could have a repository dedicated only to handling blog posts. Search led me to git sparse checkout:

1. Initialize a git repository

      $ git init <name>
   

2. Configure to enable sparse checkouts:

      $ git config core.sparsecheckout true
   

3. Edit .git/info/sparse-checkout to include the target file or directory.

      $ echo target/directory/or/file >> .git/info/sparse-checkout
   

4. Add remote:

      $ git remote add -f origin https//github.com/my_github/project.git
   

5. Fetch the files

      $ git pull origin master
   

The resulting git repository should contain only the directory or file specified in .git/info/sparse-checkout (In the case above, target/directory/or/file).

Now if I could make something like an export template for exporting org subtrees as jekyll post file, it would make these blog posts so much easier to make.
