If you want a notification in your inbox that there's a New Thing published on the blog, I'll send you an email to let you know. It will be me thinking out loud, sharing reflections and learning, or talking about what I'm working on. It will probably be infrequent, at best.
There's no web archive of the newsletters because they're basically saying "hi, there's a new blog post". Head over to the blog to read previous items.
