Followers

I just have a question, and am a little confused.
I used to have a wordpress.com blog. I bought my own domain and moved to wordpress.org a while ago.

I have installed jetpack, and i have the follow button plugin that appears in the bottom right corner. this asks users for their email so they can subscribe to my blog.

what I’m wondering is if there is an option to have a follow button so that wordpress.com users can follow my wordpress.org blog and see my updates in their reader.
