It has been decided, the work will begin with the most recent posts and work it’s way further back into the archive of posts and pages. The podcast and video posts will, most likely, get tackled as separate blocks of content outside the other blog posts. The reason for that is because that type of content has a wider appeal, is easier to ingest, and is easier to separate in the archive.
The thought process is simply that, updating and repairing the most recent content will be more readily apparent to you the reader. The demand for that classic 2009 content is not high. There are a lot of broken promises, bad ideas, and more than one idea that failed to launch. Good stuff, if you like that sort of thing. Probably, there will be plenty more in the future.
