Answer: It works, but it also messes up my archive page because there is no title to put in the listing that serves as text for the link.

The lack of a title doesn't stop the site from working, and the permalink at the bottom of the post still works.

I see other bloggers doing this with the "micro blog" posts they write in their traditional blogs, and a few systems/themes provide support for title-less posts.

But in the interest of not breaking my archive page, I'm going to stick with titles for my Ode-generated social media posts.
