Observations on what you need to build a website that will be found: a presentation for the Midland MakerPlace. Unfortunately it’s been a slow summer at the MakerPlace and there were no attendees. Hopefully a future offering will get better take-up.
With browsers having built-in “Open link in new tab” functionality, it doesn’t make sense to break a basic web idiom (the back button) on a whim. Auto-opening link in a new tab/window breaks the back button and is unnecessary (because users have the ability to make that choice for themselves).
So far the upshot of this is to not expect a simple Export/Import process with WordPress, especially when it comes to the Media Library, if one wants to rebuild a site at the same domain, rather than a domain move, with the previous domain still active.
