WTF does this mean for Blogger?
Does it have a migration route for the photos?
If there's no migration route, a tool that could be created by one Google developer, it means thousands of people now have work to fix thousands of Blogger posts. Cumulatively ~48 hours of work for a tool has just turned into at least 48000 hours for everyone else.
What's worse is, people will fix their blogs but I bet Google will use broken links as (another) justification to shut down Blogger next.
That means those 48000 hours will be an utter waste of time.
If you ever needed proof Google have no fucking strategy or clue anymore this is it (that and shutting down Google Music when YouTube Music was incomplete, people just moved to competitors).
