I am setting up a new free blog on wordpress.com called https://grittygod.wordpress.com and I will be setting up a Substack account. Over the year, I will experiment to see which is the more active one and keep it. My computer savvy son-in-law tells me that the Substack one will, because I can link it to anything--an email, a facebook page, whatever I want. It will just be a matter of figuring out how to use it.
