I'm posting this in response to a sweet friend of mine asking how to become a follower of my incredibly wonderful blog.
First click on the follow button shown in the pic below.
Then you will be given a choice of whether to follow publically or privately depending on whether or not you want others (and me) to know you are following. Of course you want to publically follow this blog - cause I'll look cooler with the more followers I have.
I tested the process and signed in as a public follower using my twitter account.
