The New Blogger is Crap

Why?

With the old one, you could make a post a sticky top post simply by setting the publish date to something in the future.

Try that with the new Blogger and what do you get? You can't even see the damn post because it's "scheduled to post" on that date you set. *ds of Google!

So, what *can* you do? You can 

1. Revert to draft
2. Publish with the new (current) date

And that'll ensure you top-post 😊
