I have a small blog hosted on blogger.com
I don't understand why, when people like or share a blog post on Facebook, the real content is never fetched as a summary.
For example, for this post, the summary is the small "about me" that I placed on the sidebar, while on this other post, the summary is the first comment.
It's weird, what I can do? There is a way, for example a class, to indicate the main content div?
