Here is the long answer:
No, I have a lot more on my feed. My settings have been "Friends only" until recently as I was having problems with WordPress. I then changed it to Public this week and after I had a few more blog posts post to with the Only me setting. The posts that are showing to you I had to manually change.
Regardless of all of the above, I have never had my default settings set to "Only me." If my past behavior dictated how the posts would be set, I would assume they would have been set to "Friends only".
Now that I have taken this rather long detour of explanation, I am no closer to a solution than I was before.
I have posted the relevant information:
the Share settings of my blog
my privacy settings on facebook
the resulting post on facebook
If this is not enough information to determine a solution, I do not believe any further information will help.
