Thanks! Both great suggestions for tackling logistics!
What I'm really looking to avoid is the inevitable guilt that will accumulate once I have created my own blogging platform. Like, there is so much other stuff I should blog about and never will. And there will sit my Medium account or .Rmd, calling to me in all their neglect, joining the voices of so many other projects.
But if I tell a real person I am going to contribute to their blog just once, then I will most likely probably do it!
