Good point, John. I am pretty sure I have mine set to full text, because I remember having a similar issue with RSS readers in the past–it was annoying to just get a small snippet rather than the full post!
But that said, something weird is happening with the syndication to the Teaching with WordPress site for this post and the one right after it. On the blog hub, these just have the titles and not even a snippet of the post. What’s strange is that your latest post does show more of the post on our site. I’ll see what I can find out about that b/c now I’m curious!
