Facebook vs Blogger?
What is the difference?
Usually "FB" can obtain almost instant feedback from a reader. Whereas on Blogger, the reader creates a feedback post which is emailed to the blogger. Time consuming.
But Blogger has options on how the page is presented with a sidebar of other information.
I continue to like both...

And with the problems FB is having with security issues and censorship, their stocks recently dropped. As in any other business,
people will take their business elsewhere when they get burned.

There are alternatives out there, and they will take time for customers to learn the new software if they jump ship. Just like we did when MySpace went away. (not completely away, it is still out there somewhere). Well thats what capitalism does, if someone does not like your product and you dont compensate, then the consumer-driven product goes away.
