You can and should feel free to share my posts on social media.
You can and should feel free to re-blog my posts.
My only stipulation is that you should include a link back to the original content.
Sharing actually helps my writing spread around and it’s about the only way I’m going to get beyond my current follower count. I know some writers are against sharing things to social media–I am not. Again, presuming there is some way to get from the shared post back to my original post.
