For what it's worth..... I have added a button on my sidebar to follow me via bloglovin'. I'm still not the least bit clear about this whole changeover.... but I needed to keep up with the trend. I joined with just my email..... not through Facebook, so if you are like me and don't want any more things running on your FB page than necessary, you can join and follow through email.
(Good grief ..... why did they mess with Google and something that worked so well?!)
