Blogs

Blogs are generally not formally peer-reviewed and are generally written more informally and conversationally, but are often a great resource. With the shift from blogs to social media, many blogs have shifted to Facebook, and to a lesser extent Twitter and Reddit. (E.g., Mississippi Fred McDowel no longer posts on “On the Main Line”, but does on Facebook..) Blogs are far less active than they were. There are a lot of Facebook groups, which I’m less familiar with, and technically have to be added to and aren’t indexed by Google unfortunately (“walled gardens“, vs. “open platforms”).
