This is only a test

I'm testing the possibility of having a short intro that can expand into a longer post.

With this trick, you can choose to display an arbitrary amount of text from the beginning of each post, as a teaser for the whole thing. Then users who want to read the rest of the post can click a link to see the full text. This is handy if you have lots of long articles all on one page.

Just click your "Back" button to collapse the longer post.
