I have configured my blog index to only show posts with titles. At first, I was a little hesitant, but I think it makes for a better experience when I'm reading it. I also found that I do not hesitate as much make microposts.

Here are the steps I used to make my Micro.blog hosted blog list only the titled posts on my homepage and still paginate correctly. Note: This does require editing your blog theme.
She’s got an amazing site and you should check it out.
